    This is a fresh install of ISPConfig on CentOS 6.5 x64 following The Perfect Server Howto and this is the only thing between now and going live.

    I wish I understood this stuff more, I've been googling for a couple of days and I have searched this forum, but either couldn't find what I'm looking for, or it really doesn't exist yet.

    I am able to recieve emails (at least the initial "Welcome to your new account" email), but am unable to send.

    The log shows:
    Jan 4 07:34:25 localhost postfix/smtpd[11273]: NOQUEUE: reject: RCPT from unknown[IP Hidden]: 553 5.7.1 <valid ispconfig user email>: Sender address rejected: not owned by user valid ispconfig user email; from=<valid ispconfig user email> to=<valid external recipient email> proto=ESMTP helo=<[192.168.1.7]>

    My main.cf:
    Code:
    # Global Postfix configuration file. This file lists only a subset
    # of all parameters. For the syntax, and for a complete parameter
    # list, see the postconf(5) manual page (command: "man 5 postconf").
    #
    # For common configuration examples, see BASIC_CONFIGURATION_README
    # and STANDARD_CONFIGURATION_README. To find these documents, use
    # the command "postconf html_directory readme_directory", or go to
    # http://www.postfix.org/.
    #
    # For best results, change no more than 2-3 parameters at a time,
    # and test if Postfix still works after every change.
    
    # SOFT BOUNCE
    #
    # The soft_bounce parameter provides a limited safety net for
    # testing.  When soft_bounce is enabled, mail will remain queued that
    # would otherwise bounce. This parameter disables locally-generated
    # bounces, and prevents the SMTP server from rejecting mail permanently
    # (by changing 5xx replies into 4xx replies). However, soft_bounce
    # is no cure for address rewriting mistakes or mail routing mistakes.
    #
    #soft_bounce = no
    
    # LOCAL PATHNAME INFORMATION
    #
    # The queue_directory specifies the location of the Postfix queue.
    # This is also the root directory of Postfix daemons that run chrooted.
    # See the files in examples/chroot-setup for setting up Postfix chroot
    # environments on different UNIX systems.
    #
    queue_directory = /var/spool/postfix
    
    # The command_directory parameter specifies the location of all
    # postXXX commands.
    #
    command_directory = /usr/sbin
    
    # The daemon_directory parameter specifies the location of all Postfix
    # daemon programs (i.e. programs listed in the master.cf file). This
    # directory must be owned by root.
    #
    daemon_directory = /usr/libexec/postfix
    
    # The data_directory parameter specifies the location of Postfix-writable
    # data files (caches, random numbers). This directory must be owned
    # by the mail_owner account (see below).
    #
    data_directory = /var/lib/postfix
    
    # QUEUE AND PROCESS OWNERSHIP
    #
    # The mail_owner parameter specifies the owner of the Postfix queue
    # and of most Postfix daemon processes.  Specify the name of a user
    # account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS
    # AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM.  In
    # particular, don't specify nobody or daemon. PLEASE USE A DEDICATED
    # USER.
    #
    mail_owner = postfix
    
    # The default_privs parameter specifies the default rights used by
    # the local delivery agent for delivery to external file or command.
    # These rights are used in the absence of a recipient user context.
    # DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER.
    #
    #default_privs = nobody
    
    # INTERNET HOST AND DOMAIN NAMES
    #
    # The myhostname parameter specifies the internet hostname of this
    # mail system. The default is to use the fully-qualified domain name
    # from gethostname(). $myhostname is used as a default value for many
    # other configuration parameters.
    #
    #myhostname = host.domain.tld
    #myhostname = virtual.domain.tld
    
    # The mydomain parameter specifies the local internet domain name.
    # The default is to use $myhostname minus the first component.
    # $mydomain is used as a default value for many other configuration
    # parameters.
    #
    #mydomain = domain.tld
    
    # SENDING MAIL
    #
    # The myorigin parameter specifies the domain that locally-posted
    # mail appears to come from. The default is to append $myhostname,
    # which is fine for small sites.  If you run a domain with multiple
    # machines, you should (1) change this to $mydomain and (2) set up
    # a domain-wide alias database that aliases each user to
    # [email protected]
    #
    # For the sake of consistency between sender and recipient addresses,
    # myorigin also specifies the default domain name that is appended
    # to recipient addresses that have no @domain part.
    #
    #myorigin = $myhostname
    #myorigin = $mydomain
    
    # RECEIVING MAIL
    
    # The inet_interfaces parameter specifies the network interface
    # addresses that this mail system receives mail on.  By default,
    # the software claims all active interfaces on the machine. The
    # parameter also controls delivery of mail to user@[ip.address].
    #
    # See also the proxy_interfaces parameter, for network addresses that
    # are forwarded to us via a proxy or network address translator.
    #
    # Note: you need to stop/start Postfix when this parameter changes.

    #inet_interfaces = $myhostname, localhost
    inet_interfaces = all
    
    # Enable IPv4, and IPv6 if supported
    inet_protocols = all
    
    # The proxy_interfaces parameter specifies the network interface
    # addresses that this mail system receives mail on by way of a
    # proxy or network address translation unit. This setting extends
    # the address list specified with the inet_interfaces parameter.
    #
    # You must specify your proxy/NAT addresses when your system is a
    # backup MX host for other domains, otherwise mail delivery loops
    # will happen when the primary MX host is down.
    #
    #proxy_interfaces =
    #proxy_interfaces = 1.2.3.4
    
    # The mydestination parameter specifies the list of domains that this
    # machine considers itself the final destination for.
    #
    # These domains are routed to the delivery agent specified with the
    # local_transport parameter setting. By default, that is the UNIX
    # compatible delivery agent that lookups all recipients in /etc/passwd
    # and /etc/aliases or their equivalent.
    #
    # The default is $myhostname + localhost.$mydomain.  On a mail domain
    # gateway, you should also include $mydomain.
    #
    # Do not specify the names of virtual domains - those domains are
    # specified elsewhere (see VIRTUAL_README).
    #
    # Do not specify the names of domains that this machine is backup MX
    # host for. Specify those names via the relay_domains settings for
    # the SMTP server, or use permit_mx_backup if you are lazy (see
    # STANDARD_CONFIGURATION_README).
    #
    # The local machine is always the final destination for mail addressed
    # to user@[the.net.work.address] of an interface that the mail system
    # receives mail on (see the inet_interfaces parameter).
    #
    # Specify a list of host or domain names, /file/name or type:table
    # patterns, separated by commas and/or whitespace. A /file/name
    # pattern is replaced by its contents; a type:table is matched when
    # a name matches a lookup key (the right-hand side is ignored).
    # Continue long lines by starting the next line with whitespace.
    #
    # See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS".

    #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,
    #       mail.$mydomain, www.$mydomain, ftp.$mydomain
    
    # REJECTING MAIL FOR UNKNOWN LOCAL USERS
    #
    # The local_recipient_maps parameter specifies optional lookup tables
    # with all names or addresses of users that are local with respect
    # to $mydestination, $inet_interfaces or $proxy_interfaces.
    #
    # If this parameter is defined, then the SMTP server will reject
    # mail for unknown local users. This parameter is defined by default.
    #
    # To turn off local recipient checking in the SMTP server, specify
    # local_recipient_maps = (i.e. empty).
    #
    # The default setting assumes that you use the default Postfix local
    # delivery agent for local delivery. You need to update the
    # local_recipient_maps setting if:
    #
    # - You define $mydestination domain recipients in files other than
    #   /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
    #   For example, you define $mydestination domain recipients in
    #   the $virtual_mailbox_maps files.
    #
    # - You redefine the local delivery agent in master.cf.
    #
    # - You redefine the "local_transport" setting in main.cf.
    #
    # - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
    #   feature of the Postfix local delivery agent (see local(8)).
    #
    # Details are described in the LOCAL_RECIPIENT_README file.
    #
    # Beware: if the Postfix SMTP server runs chrooted, you probably have
    # to access the passwd file via the proxymap service, in order to
    # overcome chroot restrictions. The alternative, having a copy of
    # the system passwd file in the chroot jail is just not practical.
    #
    # The right-hand side of the lookup tables is conveniently ignored.
    # In the left-hand side, specify a bare username, an @domain.tld
    # wild-card, or specify a [email protected] address.

    # The unknown_local_recipient_reject_code specifies the SMTP server
    # response code when a recipient domain matches $mydestination or
    # ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty
    # and the recipient address or address local-part is not found.
    #
    # The default setting is 550 (reject mail) but it is safer to start
    # with 450 (try again later) until you are certain that your
    # local_recipient_maps settings are OK.
    #
    unknown_local_recipient_reject_code = 550
    
    # TRUST AND RELAY CONTROL
    
    # The mynetworks parameter specifies the list of "trusted" SMTP
    # clients that have more privileges than "strangers".
    #
    # In particular, "trusted" SMTP clients are allowed to relay mail
    # through Postfix.  See the smtpd_recipient_restrictions parameter
    # in postconf(5).
    #
    # You can specify the list of "trusted" network addresses by hand
    # or you can let Postfix do it for you (which is the default).
    #
    # By default (mynetworks_style = subnet), Postfix "trusts" SMTP
    # clients in the same IP subnetworks as the local machine.
    # On Linux, this does works correctly only with interfaces specified
    # with the "ifconfig" command.
    #
    # Specify "mynetworks_style = class" when Postfix should "trust" SMTP
    # clients in the same IP class A/B/C networks as the local machine.
    # Don't do this with a dialup site - it would cause Postfix to "trust"
    # your entire provider's network.  Instead, specify an explicit
    # mynetworks list by hand, as described below.
    #
    # Specify "mynetworks_style = host" when Postfix should "trust"
    # only the local machine.
    #
    #mynetworks_style = class
    #mynetworks_style = subnet
    #mynetworks_style = host
    
    # Alternatively, you can specify the mynetworks list by hand, in
    # which case Postfix ignores the mynetworks_style setting.
    #
    # Specify an explicit list of network/netmask patterns, where the
    # mask specifies the number of bits in the network part of a host
    # address.
    #
    # You can also specify the absolute pathname of a pattern file instead
    # of listing the patterns here. Specify type:table for table-based lookups
    # (the value on the table right-hand side is not used).
    #
    #mynetworks = 168.100.189.0/28, 127.0.0.0/8
    #mynetworks = $config_directory/mynetworks
    #mynetworks = hash:/etc/postfix/network_table
    
    # The relay_domains parameter restricts what destinations this system will
    # relay mail to.  See the smtpd_recipient_restrictions description in
    # postconf(5) for detailed information.
    #
    # By default, Postfix relays mail
    # - from "trusted" clients (IP address matches $mynetworks) to any destination,
    # - from "untrusted" clients to destinations that match $relay_domains or
    #   subdomains thereof, except addresses with sender-specified routing.
    # The default relay_domains value is $mydestination.
    #
    # In addition to the above, the Postfix SMTP server by default accepts mail
    # that Postfix is final destination for:
    # - destinations that match $inet_interfaces or $proxy_interfaces,
    # - destinations that match $mydestination
    # - destinations that match $virtual_alias_domains,
    # - destinations that match $virtual_mailbox_domains.
    # These destinations do not need to be listed in $relay_domains.
    #
    # Specify a list of hosts or domains, /file/name patterns or type:name
    # lookup tables, separated by commas and/or whitespace.  Continue
    # long lines by starting the next line with whitespace. A file name
    # is replaced by its contents; a type:name table is matched when a
    # (parent) domain appears as lookup key.
    #
    # NOTE: Postfix will not automatically forward mail for domains that
    # list this system as their primary or backup MX host. See the
    # permit_mx_backup restriction description in postconf(5).
    #
    #relay_domains = $mydestination
    
    # INTERNET OR INTRANET
    
    # The relayhost parameter specifies the default host to send mail to
    # when no entry is matched in the optional transport(5) table. When
    # no relayhost is given, mail is routed directly to the destination.
    #
    # On an intranet, specify the organizational domain name. If your
    # internal DNS uses no MX records, specify the name of the intranet
    # gateway host instead.
    #
    # In the case of SMTP, specify a domain, host, host:port, [host]:port,
    # [address] or [address]:port; the form [host] turns off MX lookups.
    #
    # If you're connected via UUCP, see also the default_transport parameter.

    # REJECTING UNKNOWN RELAY USERS
    #
    # The relay_recipient_maps parameter specifies optional lookup tables
    # with all addresses in the domains that match $relay_domains.
    #
    # If this parameter is defined, then the SMTP server will reject
    # mail for unknown relay users. This feature is off by default.

    # INPUT RATE CONTROL
    #
    # The in_flow_delay configuration parameter implements mail input
    # flow control. This feature is turned on by default, although it
    # still needs further development (it's disabled on SCO UNIX due
    # to an SCO bug).
    #
    # A Postfix process will pause for $in_flow_delay seconds before
    # accepting a new message, when the message arrival rate exceeds the
    # message delivery rate. With the default 100 SMTP server process
    # limit, this limits the mail inflow to 100 messages a second more
    # than the number of messages delivered per second.
    #
    # Specify 0 to disable the feature. Valid delays are 0..10.
    #
    #in_flow_delay = 1s
    
    # ADDRESS REWRITING
    #
    # The ADDRESS_REWRITING_README document gives information about
    # address masquerading or other forms of address rewriting including
    # username->Firstname.Lastname mapping.

    # ALIAS DATABASE
    #
    # The alias_maps parameter specifies the list of alias databases used
    # by the local delivery agent. The default list is system dependent.
    #
    # On systems with NIS, the default is to search the local alias
    # database, then the NIS alias database. See aliases(5) for syntax
    # details.
    #
    # If you change the alias database, run "postalias /etc/aliases" (or
    # wherever your system stores the mail alias file), or simply run
    # "newaliases" to build the necessary DBM or DB file.
    #
    # It will take a minute or so before changes become visible.  Use
    # "postfix reload" to eliminate the delay.

    #alias_maps = dbm:/etc/aliases
    alias_maps = hash:/etc/aliases
    #alias_maps = hash:/etc/aliases, nis:mail.aliases
    #alias_maps = netinfo:/aliases
    
    # The alias_database parameter specifies the alias database(s) that
    # are built with "newaliases" or "sendmail -bi".  This is a separate
    # configuration parameter, because alias_maps (see above) may specify
    # tables that are not necessarily all under control by Postfix.

    # ADDRESS EXTENSIONS (e.g., user+foo)
    #
    # The recipient_delimiter parameter specifies the separator between
    # user names and address extensions (user+foo). See canonical(5),
    # local(8), relocated(5) and virtual(5) for the effects this has on
    # aliases, canonical, virtual, relocated and .forward file lookups.

    # DELIVERY TO MAILBOX
    #
    # The home_mailbox parameter specifies the optional pathname of a
    # mailbox file relative to a user's home directory. The default
    # mailbox file is /var/spool/mail/user or /var/mail/user.  Specify
    # "Maildir/" for qmail-style delivery (the / is required).
    #
    #home_mailbox = Mailbox
    #home_mailbox = Maildir/
    
    # The mail_spool_directory parameter specifies the directory where
    # UNIX-style mailboxes are kept. The default setting depends on the
    # system type.
    #
    #mail_spool_directory = /var/mail
    #mail_spool_directory = /var/spool/mail
    
    # The mailbox_command parameter specifies the optional external
    # command to use instead of mailbox delivery. The command is run as
    # the recipient with proper HOME, SHELL and LOGNAME environment settings.
    # Exception:  delivery for root is done as $default_user.
    #
    # Other environment variables of interest: USER (recipient username),
    # EXTENSION (address extension), DOMAIN (domain part of address),
    # and LOCAL (the address localpart).
    #
    # Unlike other Postfix configuration parameters, the mailbox_command
    # parameter is not subjected to $parameter substitutions. This is to
    # make it easier to specify shell syntax (see example below).
    #
    # Avoid shell meta characters because they will force Postfix to run
    # an expensive shell process. Procmail alone is expensive enough.
    #
    # IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
    # ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.

    #mailbox_command = /some/where/procmail -a "$EXTENSION"
    
    # The mailbox_transport specifies the optional transport in master.cf
    # to use after processing aliases and .forward files. This parameter
    # has precedence over the mailbox_command, fallback_transport and
    # luser_relay parameters.
    #
    # Specify a string of the form transport:nexthop, where transport is
    # the name of a mail delivery transport defined in master.cf.  The
    # :nexthop part is optional. For more details see the sample transport
    # configuration file.
    #
    # NOTE: if you use this feature for accounts not in the UNIX password
    # file, then you must update the "local_recipient_maps" setting in

    # If using the cyrus-imapd IMAP server deliver local mail to the IMAP

    #
    # mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp

    # local_destination_concurrency_limit = 5
    #
    # Of course you should adjust these settings as appropriate for the
    # capacity of the hardware you are using. The recipient limit setting
    # can be used to take advantage of the single instance message store
    # capability of Cyrus. The concurrency limit can be used to control
    # how many simultaneous LMTP sessions will be permitted to the Cyrus
    # message store.
    #
    # To use the old cyrus deliver program you have to set:

    # to use for recipients that are not found in the UNIX passwd database.
    # This parameter has precedence over the luser_relay parameter.

    #
    # The controls listed here are only a very small subset. The file
    # SMTPD_ACCESS_README provides an overview.
    
    # The header_checks parameter specifies an optional table with patterns
    # that each logical message header is matched against, including
    # headers that span multiple physical lines.
    #
    # By default, these patterns also apply to MIME headers and to the
    # headers of attached messages. With older Postfix versions, MIME and
    # attached message headers were treated as body text.

    # FAST ETRN SERVICE
    #
    # Postfix maintains per-destination logfiles with information about
    # deferred mail, so that mail can be flushed quickly with the SMTP
    # "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld".
    # See the ETRN_README document for a detailed description.
    #
    # The fast_flush_domains parameter controls what destinations are
    # eligible for this service. By default, they are all domains that
    # this server is willing to relay mail to.
    #
    #fast_flush_domains = $relay_domains
    
    # SHOW SOFTWARE VERSION OR NOT
    #
    # The smtpd_banner parameter specifies the text that follows the 220
    # code in the SMTP server's greeting banner. Some people like to see
    # the mail version advertised. By default, Postfix shows no version.
    #
    # You MUST specify $myhostname at the start of the text. That is an
    # RFC requirement. Postfix itself does not care.
    #
    #smtpd_banner = $myhostname ESMTP $mail_name
    #smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)
    
    # PARALLEL DELIVERY TO THE SAME DESTINATION
    #
    # How many parallel deliveries to the same user or domain? With local
    # delivery, it does not make sense to do massively parallel delivery
    # to the same user, because mailbox updates must happen sequentially,
    # and expensive pipelines in .forward files can cause disasters when
    # too many are run at the same time. With SMTP deliveries, 10
    # simultaneous connections to the same domain could be sufficient to
    # raise eyebrows.
    #
    # Each message delivery transport has its XXX_destination_concurrency_limit
    # parameter.  The default is $default_destination_concurrency_limit for
    # most delivery transports. For the local delivery agent the default is 2.
    
    #local_destination_concurrency_limit = 2
    #default_destination_concurrency_limit = 20
    
    # DEBUGGING CONTROL
    #
    # The debug_peer_level parameter specifies the increment in verbose
    # logging level when an SMTP client or server host name or address
    # matches a pattern in the debug_peer_list parameter.
    #
    debug_peer_level = 2
    
    # The debug_peer_list parameter specifies an optional list of domain
    # or network patterns, /file/name patterns or type:name tables. When
    # an SMTP client or server host name or address matches a pattern,
    # increase the verbose logging level by the amount specified in the
    # debug_peer_level parameter.
    #
    #debug_peer_list = 127.0.0.1
    #debug_peer_list = some.domain
    
    # The debugger_command specifies the external command that is executed
    # when a Postfix daemon program is run with the -D option.
    #
    # Use "command .. & sleep 5" so that the debugger can attach before
    # the process marches on. If you use an X-based debugger, be sure to
    # set up your XAUTHORITY environment variable before starting Postfix.

    Are you able to send Email to a local address? If yes, then sour problem is most likely related to the fact that the server is not live yet.

    Nice to hear that you like my software ISPConfig :)

    :O If I got the wrong person, or perhaps ISPConfig is bigger than just one person, sorry.

    I do love your software, Till!

    Using SquirrelMail, I am able to send email to any address I want. Using ThunderBird receiving mail works just fine, but fails with the aforementioned error. I think that it is a postfix auth problem, but I don't know how to fix it :(

    Thanks in advance!!

    Thanks :) I'am the original author and project manager of the ISPConfig Software and Falko is writing most if ur Tutorials :) But I'am not the only developer, there are several other users helping in ISPConfg development and if Falko has some free time, he contributes code as well.

    Are there any other errors in the mail.log file, e.g. sasl errors? May you please post all lines that get added to mail.log wen you try to send a email to a external address?

    Are you able to send a email with thnderbird to the address of the account that you created in thunderbird (a email to yourself)?

    Regarding master.cf, please change these lines:

    Code:
    smtp      inet  n       -       n       -       -       smtpd
    submission inet n       -       n       -       -       smtpd

    Edited because I forgot to answer:
    There weren't before, but this TLS issue below is now showing up. saslauthd is running and appears to be fine.
    Shown below, and this occurs when sending an email to any address, not just local ones, but only from an external client like Thunderbird.
    No, but I can from the local client SquirrelMail, shown below.

    Well, that certainly changed things. Now the log looks like this
    Code:

    Sending an email from SquirrelMail produces a successfully sent email and this log

    I followed the howto religiously, the only issue came when I was installing mailman and that was because the aliases db hadn't been created yet. I also read that the dovecot.conf was pointing to /etc/dovecot-sql.conf when it should have been pointing at /etc/dovecot/dovecot-sql.conf but I don't see how that would produce these results.

    Thanks again for your help!!

    An update:
    I ran the ISPConfig's /tmp/ispconfig3_install/install/update.php and updated the services, configurations, etc, made sure the suggested changes were taking place.

    I also regenerated keys and certs for postfix/dovecot and made sure to use the fqdn of the server (not the hostname)

    This one seems a little telling as there are some TLS issues in the beginning and then the "not owned by user" thing comes up again.

    Public vs. NAT IP Address

    FYI, I have a very-similar configuration to yours (CentOS 6.5 x86_64 with dovecot and Apache following the Perfect Server HowTo). The main difference is that I built my server on a public IP address since I've had a lot of grief in the past with building my server on a NAT IP address and then expecting things to work OK. So the first thing I did before building my server was to obtain a public IP address and ensure that Reverse DNS was properly build to point back to my server name at my public IP address.

    With that said I have not had any large issues with getting other mail servers to accept my output email messages. AOL bounced me due to too many reports on my (brand new) IP address, but I rather think they confused my Comcast Business IP address with a general home user IP address, which isn't the least bit fair as I have my incoming email filtered by Postini/Google and nobody else can get to port 25 due to iptables filtering (as a Cisco professional routing engineer, if you needed iptables help I could fix you right up; iptables has a lot in common with router access lists).

    Anyway, I was concerned about this part of your error message: "helo=<[192.168.1.7]>"

    That doesn't seem to be the correct "helo" message. If you are trying to connect to something outside of your own LAN, then in fact that IP address isn't owned by you when you get to the other side. You might want to take a look at that.

    Good eye, but that's from Thunderbird out of my home. The server is sitting straight on the internet, with its own static IP and is able to send email to any of my other addresses (from SquirrelMail sitting locally on the box) just fine, including my hotmail address and gmail.

    It's when I'm trying to send from outside the box, not from localhost(127.0.0.1) that this is happening. As in, logging onto Postfix from home, authing, handing the message over, and logging out. Dovecot does all this just fine, Postfix is being elusive.

    Thanks for the consideration, though.

    Out of time limits, I took the plunge and put it all live.

    I HATE putting it up live before it's all working, but here it is.

    I moved it live and not it's OK, I can send, receive, et al.

    Till, Falko, can either of you Linuxheads tell me why?

    I'd surely appreciate it!!

    I still love you people, with no end. Rainbows and happiness, the hot girl that once friendzoned you, I wish you guys everything.

    That looks like that that there's maybe a problem with your SMTP Server configuration?! Just a guess.

    I had similar problems once and changed the SMTP to use the SMTP Server of mi ISP, which is an Open Relay Server. Using several Domains, each with it's own Mail-Server Domain and set my Desktop and Laptop Mail Client's TheBat Pro for all to mail.mydomain.com (while mydomain.com is the actual Domain name). Only in ISPConfig I had set in System ->Server Config under the Mail tap the Relay Host to the SMTP of my ISP. That just works fine for send an receive Mails from any location.

    By the way, I didn't use the DNS Zones in ISPConfig, because I use 1 static/public IP only, I use A Records via the Domain Registras and their Nameservers to point to my static IP.

    There is a problem with the ssl cert from postfix. It seems to be broken. You can create a new ssl cert for postfix like this:

    Code:
    cd /etc/postfix/tls
    openssl req -new -outform PEM -out smtpd.cert -newkey rsa:4096 -nodes -keyout smtpd.key -keyform PEM -days 3650 -x509


    If it works from localhost, then the smtp server setup is corect and working fine.

    Have you checked your dns records? Is the mx record of your domain pointing to the hostname of your server, does the hostname of the server exist in dns, does the external IP of the server ahs a reverse record? s there any firewall in front of your server or a router, which might block some connections?

    Ok, now I don't see the TLS error in the log, thanks!!
    I've moved the server to fully live in hopes that it was an issue of being quasi-up. All DNS records point to this server now, just like they did to the old, CentOS 5/ISPConfig server (that worked totally great, thanks!!) Yes, MX does point to this server, it does have a DNS entry that can be dug at jechosting.com.

    No firewall or router, this machine sits directly on the internet.

    Reverse DNS comes up with a hostname that Comcast assigned (this is a business account with a static IP) so I've fixed my hostname to match that.

    The maillog is down to

    So now, until I get this figured out, my email is down and I'm going to go seriously bonkers.

    Thanks for any help I can get.

    Ok, I don't know if this is the way it's supposed to be or not, but in master.cf:
    Code:
    submission inet n - - - - smtpd
      -o smtpd_tls_security_level=encrypt
      -o smtpd_sasl_auth_enable=yes
      -o smtpd_sasl_type=dovecot
      -o smtpd_sasl_path=private/auth
      -o smtpd_sasl_security_options=noanonymous
      -o smtpd_sasl_local_domain=$myhostname
      -o smtpd_client_restrictions=permit_sasl_authenticated,reject
      -o smtpd_sender_login_maps=hash:/etc/postfix/virtual
      -o smtpd_sender_restrictions=[B][SIZE="4"][COLOR="Red"]reject_sender_login_mismatch[/COLOR][/SIZE][/B]
      -o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject
    
    was causing the issue. I don't know if it's a big security hole to take that out, but without it, I can send email again just fine.

    If you want to allow your users to send with sender addresses that differ from their mailbox login, then its ok to remove that.

    As a sidenote: I guess you replaced email addresses a bit unclear in the log lines:

    Jan 7 08:34:05 host postfix/smtpd[16948]: NOQUEUE: reject: RCPT from unknown[my.home.ip]: 553 5.7.1 <[email protected]>: Sender address rejected: not owned by user [email protected]; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<[192.168.1.7]>
    ....
    Jan 7 08:37:44 host dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=my.home.ip, lip=isp.configs.ip.address, mpid=17054, TLS

    as the addresses in the line must have been different if the issue was caused by "smtpd_sender_restrictions=reject_sender_login_mismatch" becase in the log you posted is the sender address and login address the same.

    IMAP/Dovecot works fine. That was the whole of the important bits of the log, before that was just after I restarted dovecot/postfix/saslauthd and there were just startup messages.

    Anyway, it's running fine for now, I'll ponder what to do later, for now, I'm going to give it a rest.

    Thanks again for your help and for ISPConfig!!

    Gruss Gott! (I don't have the umlauts and the backwards B on my keyboard)
