RH9 SMTP/POP3 problems

I am hoping someone will recognize some of the symptoms that I am
experiencing and be able to suggest a direction for a cure.  I have a couple
of servers who's primary role is email.  These are all RH9 updated via
FL/apt-get with all current and available patches applied.  I am also
running Spamassassin/spamass milter/vexira.  99% of my users are using
Outlook Express for their clients.  Frequently, when the users try to send
email, they get a message that the Server Unexpectedly Terminated the
connection and the message does not get sent.  After some time passes....the
message will eventually be sent.  I have poured over the logs and cannot
seem to find anything that would suggest a pattern.  I have checked TOP and
FREE to see if maybe the server is overloaded and that has not been the
case.  I have checked the firewall and tightened up a thing here and there
but nothing that would seem to be related....though I did see one of those
/220/220/220/220 gethostbyname entries.  I am not running anything that
should be vulnerable to that exploit though.  Any suggestions?  Anything
else I can check?  I am beginning to suspect that the problem may be in a
module that was updated recently but am not sure.

Thanks guys!
