Mail problems - Loop & Relay

[yap]

Hallo,

I have Suse 9.2 running on my server a long time. Yesterday I installed ISPConfig and it runs very good. Before I installed ISPConfig I followed the install guide for Suse 9.2. But now I have two problems with my mails:

Problem 1: I can't send mails from an external pc over SMTP to an external mail address. In the mail program I get an error that Relaying is not allowed. In the mail.log stands this:

Nov 12 18:44:05 linux postfix/smtpd[28079]: connect from x.y.z[x.y.z]
Nov 12 18:44:05 linux postfix/smtpd[28079]: NOQUEUE: reject: RCPT from x.y.z[x.y.z]: 554 <me@gmx.de>: Relay access denied; from=<info@example.com> to=<me@gmx.de> proto=SMTP helo=<PC1>
Nov 12 18:44:05 linux postfix/smtpd[28079]: disconnect from x.y.z[x.y.z]

Problem 2: I also installed the webmail interface for testing. Sending to an external mail adress is no problem. If i send an email to my local or to another local mail address then I get this:

Nov 12 18:54:58 linux postfix/smtp[28261]: 6ED992B825: to=<info@example.com>, relay=none, delay=0, status=bounced (mail for example.com loops back to myself)
Nov 12 18:54:58 linux postfix/cleanup[28260]: B29D92B875: message-id=<20051112175458.B29D92B875@server1.mydomain.de>

Nov 12 18:54:59 linux postfix/qmgr[26121]: B29D92B875: removed

What is wrong?

Thanks!

Problem 1) You have to enable SMTP-Auth in your email client. In outlook this option is named like smtp server needs authentication.

Problem 2) Put the domain that loops back (example.com) at the end of the

/etc/postfix/local-host-names

file and then restart postfix

/etc/init.d/postfix restart

[yap]

Thank you till,

I tested the sending of mails with Outlook Express and Thunderbird. In Outlook I checked the opton "SMTP server needs authentication". On Thunderbird I use "Use username and password". But the problem is still the same.

The domain is already in /etc/postfix/local-host-names.

It's very strange?! Any other ideas? I searched the forum already but I still haven't found anything like that.

Perhaps it's easier when I show my /etc/postfix/main.cf:

mydomain = anotherdomain.de
myhostname = server1.$mydomain
smtpd_sasl_local_domain =
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
inet_interfaces = all
alias_maps = hash:/etc/aliases
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtpd_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom

No, that can't be!
Please post the exact error message from your mail log and the contents of /etc/postfix/local-host-names, and don't replace the real domain names with example.com.

Ok here is my /etc/postfix/local-host-names:

###################################
#
# ISPConfig local-host-names Configuration File
#         Version 1.0
#
###################################
localhost
server1.domain1.de
localhost.server1.domain1.de
localhost.domain1.de
www.domain2.de
domain2.de
#### MAKE MANUAL ENTRIES BELOW THIS LINE! ####
server1
domain1.de

and here the /etc/postfix/main.cf again:

mydomain = domain1.de
myhostname = server1.$mydomain
smtpd_sasl_local_domain =
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
inet_interfaces = all
alias_maps = hash:/etc/aliases
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtpd_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom

In Yast under network I have server1 as host name and domain1.de as domain name.

And here the error if I send an email from info(at)domain2.de to mail(at)domain2.de over the webinterface:

And I get this error when I send mail from Outlook (Server need authentication is activated!):

Please put the following two lines into /etc/postfix/main.cf and restart Postfix:

virtual_maps = hash:/etc/postfix/virtusertable
mydestination = /etc/postfix/local-host-names

[yap]

now it works! thank you very much
