Subject: 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!
