font-family:Arial'>I have a Dapper server that I did the LAMP setup on, then I
installed postfix and mailscanner. What I’m trying to do is build an
SMTP gateway that receives mail, filters out spam and forwards on to my
exchange server. I think postfix is up and running but how can I check to see
if it is? Is there not a walkthrough somewhere of how to test postfix? Also,
how do I see what ports are listening on my Dapper box, and could I telnet into
port 25 and test that way?<o:p></o:p></span></font></p>
