I installed squirrelmail and have dovecot and sendmail running....

I can log into squirrelmail and actually SEND mail to anyone (tried to send it to my hotmail acct and received it).

but I cannot receive any mail.. no error, no bouncebacks, nothing...

What could be the problem?

The MX record on the domain is pointed directly at my server's IP.

Could be a number of things. Have you checked to make sure that sendmail is listening for external connections. IIRC, the default is to only listen on the loopback interface -- you have to explicitly set it to listen on the external interface. Other things to check is whether you have a firewall on the box blocking incoming port 25 connections and whether your ISP blocks incoming port 25.

Fixed! It was the port actually, thanks.

Now I can send/receive no problem .. but finding out some mail servers don't accept incoming mail from domain names that have no reverse DNS records....dang!
