Postfix installation and configuration problem

[kdomrose]

Greetings,

I am hoping someone might be able to help out here, or get me going in the right direction.

I am attempting to setup a mail server and it is kicking my arse. :P

Been trying now for about 2 weeks..

I have Ubuntu 8.04 for an os

I have installed LAMP server and SSH

I have been following several different how to guides... I have reinstalled Linux between attempts so i always started out fresh.

The latest guide I have tried is this one http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04-p4

I really would like the virtual users and domains thing...

I believe I have followed the guide but somewhere something is wrong.

When I attempt to telnet to the localhost 25 to test postfix I get the following


root@tweety:/home/centechadmin# telnet mail.centechcomputers.com 25 Trying 65.15.185.110...
Connected to centechcomputers.com.
Escape character is '^]'.
Connection closed by foreign host.
root@tweety:/home/centechadmin#

The pop3 seems to be working fine

My postfix/main.cf file is as follows

myhostname = mail.centechcomputers.com
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu/GNU)
biff = no
append_dot_mydomain = no
myorigin = centechcomputers.com
mydestination = %myhostname, localhost, localhost.localdomain
mynetworks = 127.0.0.1/8
recipient_delimiter = +
inet_interfaces = all
proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domain $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps
readme_directory = /usr/share/doc/postfix
html_directory = /usr/share/doc/postfix/html
mydestination = mail.centechcomputers.com, localhost, localhost.localdomain
virtual_alias_domains =
virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf
virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf
virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf
virtual_mailbox_base = /home/vmail
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000
smtpd_sasl_auth_enabled = yes
broken_sasl_auth_clients = yes
smtpd_sasl_authenticated_header = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
smtpd_use_tls = yes
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.key
transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = "The user you are trying to reach is over quota."
virtual_overquota_bounce = yes
content_filter = amavis:[127.0.0.1]:10024
receive_override_options = no_address_mappings

anyone see anything obvious????

Thanks in advance for any advice.

Ok..I found an error in my main.cf file.... had 127.0.0.1/8 instead of 127.0.0.0/8

Now I can at least get some output from the telnet session. I and still not getting the correct output....Not giving me the 250-AUTH LOGIN PLAIN

Will keep digging..

Ok...I discovered that I totally missed creating one of the MySQL tables needed...DOAH!!!!!

I created it and now when I send a test email to the server it gets rejected with relaying is denied error

I sent the email from an external account.

The error was in a bounce message i got back.

Failed to deliver to 'centechadmin@centechcomputers.com'
SMTP module(domain centechcomputers.com) reports:
host mail.centechcomputers.com says:
554 5.7.1 <centechadmin@centechcomputers.com>: Relay access denied

Now I don't know where to look to figure this one out.....

Here is from the mail log

I got the darn thing to send out an email my changing mynetworks parameter.

I didn't think I needed to add my ip range into it as I had setup for virtual users and domains.... Kinda going to stink when one of us travels and is on a different ip scheme... any suggestions??? I really DON'T want to restrict ip ranges...I am willing to rely on password login to keep people from relaying...Can this be done????

On another note..I still can not receive mail...It seems to get delivered into the que...and then goes away it seems...not able to get it...

OK...

I installed Squirrelmail and it is working fine...

I can send and receive mail using Squirrelmail fine.

I can not pull mail that is sent to the server using Mozilla Thunderbird on another computer.

Example...

I go into Thunderbird and send a message from an account on my new mail server it is delivered fine. If I send mail to the account on my mail server I can not retrieve it with Thunderbird. If I login to Squirrelmail then it is sitting there in the inbox..So the mail is moving....I just can't pull it from a remote machine.....

Suggestions??? Would this be a setting in the Postfix/Main.cf???

You must enable "Server requires authentication" in your email client.

I go into Thunderbird and send a message from an account on my new mail server it is delivered fine. If I send mail to the account on my mail server I can not retrieve it with Thunderbird. If I login to Squirrelmail then it is sitting there in the inbox..So the mail is moving....I just can't pull it from a remote machine.....Are there any errors in /var/log/mail.log?

Falco,

Thanks for the assist..

I turned on server authentication in email client..I should have thought of that...

sad to report that makes no difference... The client says it connects and just sits there...never pulls email..

Here is the tail of the mail log

Sep 19 12:15:11 tweety postfix/smtp[5147]: 120CC2E1B3: to=<centechadmin@centechcomputers.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=13, delays=0.38/0/0.02/12,$

It seems to connect then disconnect....To be fair I am NOT the worlds greatest at figuring out what logs are telling you...

I also broke my Squirrelmail install somehow playing around...Back to square one on that...

Any ideas on this POP thing???

Karl

[kdomrose]

got it fixed...just a setting in the config file for squirrelmail.

Now back after the postfix issue...

Karl

[kdomrose]

Got is all working now!!

Dumbass I was..I checked server needs authentication and never checked SSL

all good now..Thanks for the assist!!!
