Need Help with Squirrelmail

[Marcio A. Regalado]

Hello everybody

I'm trying to get a mail server running and I'm following the directions 
postend on qmailrocks.org everything has gone right 'till I get to the 
13th step "Installing Squirrelmail", it installs right and have no 
errors during installation nor configuration but when I try to log in to 
any of the mail accounts created I get the following error:

Error connecting to IMAP server: publimotion.com.mx.
110 : Connection timed out

publimotion.com.mx is the name of my server it is aliased from 
mail.publimotion.com.mx

Can you guys please point me in the right direction?
