Squirell Mail Help

[Insurrection]

Alright here is my problem:

I have just installed squirellmail.

I am using Washinton Univeristy IMAP
Newest PHP is installed
Redhat 7.3

I have the server settings pointing to:

IMAP
/usr/sbin/imapd
Port 143

Sendmail
/usr/sbin/sendmail
port 25

I can send mail and recieve mail fine from my localbox to the outside world.

So, i followed all the docs that came with Squirellmail and i can go to mydomain/squirrelmail and get the login page.

** BUT ** every single time it get it can not reach my mail server. I have spent the last 3 hours looking over google and nothing.

Please help me :D

thxks
