I have installed Postfix, Dovecot, and Squirrelmail on a CentOS 5.5 machine. In Squirrelmail a user can send mail, but he is not receiving replies. There is nothing relevant in the maillog other than the user's (successful) login attempts. I am at loss, I have been following tutorials such as the Perfect Server [1] series and other Google results, but I cannot get this thing to receive mail. What should I be checking?
Thanks!

You will want to check your DNS and try to telnet to the server. If your server is behind NAT or you run split-dns it would be advisable to try it from another connection.
dig mx yourdomain.com telnet smtp.yourdomain.com 25
Of course if your mx record points to something other than smtp.yourdomain.com you will want to use that instead.
