    I tested my mail configs using a yahoo account. When I'd got it to the point where I could send and received messages through to my own and other users mailboxes on my server, I stopped tweaking it

    but testing from telnet is a very important skill. this doesn't require you to install the telnet server though and I believe the telnet client should already be available.

    telnet send email - Google Search

    very very handy, that way you aren't waiting to see if its a network problem or waiting on another host to connect to your server.
