Mail not reaching destination

[Jason]

When sending out email, the sender is not recieveing the
email. No error message is returned to the sender, the
mail is sent successufly and looks like everything is fine.

POP3 and SMTP addresses are set up properly.

Any clues?

My firm was having this same problem- and it started when
the MYDOOM hit the air waves. Check and see if there is
a third party that is scanning your mail for viruses
and/or spam- in their attempt to stop the virus they may
have been over zealous in their settings.
If that is not an option or does not help- sorry. But it
turned out to be our problem.
