Did you simply try to open a telnet session to your servers SMTP port and check for response?
Can you see any activity in the SMTP logs?

Bolong,

Secsol gave some good tips. From what I understand its incoming mail, so mail sent from outside like GMail to your server. What error message did the sender receive? Does it happen only with some remote systems? They can check their logs. Or you can try to send from some other mail server whose logs you have access to and check the logs and try to telnet to your box from this other server.

Receiving mail is related with MX, see if your MX is setup up accordingly. Check if port 25 is open for incoming connections on your box.

regards,
Marcio
