Postfix / Dovecot Mail Issue

carlosinfl · 05-05-2009, 01:20 PM

I just installed CentOS 5.3 + Postfix + Dovecot and followed the setup instructions on this link.

Postfix is installed and running:

Code:

[root@nat ~]# /etc/init.d/postfix status
master (pid 3388) is running...

Now I am able to telnet to my server fine:

Code:

[root@nat ~]# telnet localhost smtp
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Now when I check, Jason did receive my email.

Code:

I love you!

However when I attempt to send mail via my mail client (Thunderbird), the message looks as if it sends however nobody ever gets it. I check the mail queue and it shows mail queue is empty. Anyone know what is wrong? I am sure its something silly but I don't know if it's Postfix or Dovecot.

It won't be Dovecot, because that has nothing to do with sending mail.

Run "postconf -n" as root and post the output (edit domain names to remain anonymous).

Thanks. The issue was simply Thunderbird.

Thanks!
