Linux Mail Server Setup and Howto Guide

Post edited 12:06 am – March 21, 2011 by xlancealotx

Think the subject covered it  :)    Well I used this link http://www.linuxmail.info/mult…..entos-5/  as I am running CentOS and wanted to go with MySQL.  So following the excellent docs and howto, I have mysql setup, got postfix admin setup and working, added my domains, users, dovecot, and stuck at the receive mail part.

I want to use roundcube as the web front end, but even ignoring that, I can login via telnet and send mail outside to gmail/yahoo, etc.  When I reply, I don't get a boune, but when I login even via telnet, type list I get 0 messages.

Here is where I am stuck, and naturally need this running by yesterday!  But it is what it is, I am not sure what I should provide, (or how), but the setup is straight from the above URL.  CentOS 5, apache, PHP, postfix are all the basic binary installs, but the no bounce to me means it's getting to the server, right?  I have the FW disabled, and the only thing I notice is the following.  If I run this remotely;

telnet mail.domain.com pop3

Trying x.x.x.x…

Connected to mail.domaincom.

Escape character is '^]'.

+OK Dovecot ready.

user lance@domain1.com

+OK

pass passhere

+OK Logged in.

list

+OK 0 messages:

But, roundcube uses IMAP (which is what I want), but when I try this command remotly, notice the error;

telnet mail.domain.com imap

Trying x.x.x.x…

Connected to mail.domaincom.

Escape character is '^]'.

* OK Dovecot ready.

user lance@domain.com

user BAD Error in IMAP command received by server.

Now, I am not sure if that is one problem, but either way the 1st pop list should show new mail, right?

Anyway, new to postfix but the walkthrough install was so easy I thought I would be done in no-time!  So thanks for all reads/reply's.

Made a few more dovecot tweaks, and the problem is just on recieving mail.  I can authenticate using roundcube web client, squirelmail client fine, send mail that get's delivered, but ALL mail replied or sent to the server never makes it to the user.  Firewall is disabled, so how can I check more, the sender never get's a bounce, so any help is appreciated.
