Assuming you have MX records configured correctly in DNS for the moment
the following items might cause such a problem:

1. ISP may be blocking inbound port 25.  Try using telnet outstep.com
25.  If you get a connection you should be able to type HELO domain.name
and get a response.  If you can not get a connection port 25 may be
blocked.

2. You have a firewall on your machine blocking port 25.  Same test as
in 1.  But this one you can fix by opening port 25.  Quick test would be
to issue the command:  service iptables stop.  Then run a test email to
the system or the telnet test in 1.

3. You don't have your MTA enabled on the server.  You need to have a
process listening on port 25 to receive the message.  Try the command:
netstat -an | grep :25

This should list a process listening on port 25.  If you don't have one
then you need to enable your MTA.

You can also use dig or nslookup to check your mx records.
