After talking to support on this issue, the support dept. decided to look
into this issue. While I am waiting for the result, I thought, I will ask
this usergroup if anyone has encountered similar problem:
Initially I installed Imail Small business v8.0 and the spam filtering
was working fine, by having the SMTP port changed to 1025, so that
McAfee's Webshield SMTP can use port 25 for receiving emails from the
outside world.
When the patch 8.01 came out, I installed it and voila, the spam
filtering function of Imail has stopped working, even the line
"performing antispam checks" has disappeared form the log
file.
During troubleshooting with the technical support, we figured out,
that somehow the patch 8.01 put in a pointer to port 25 into the
spamfilter code, that disregards the SMTP port entry in the advanced SMTP
setup.
The spamfilter started work again once we changed the SMTP port back
to 25 (while having all Mcafee services stopped temporarily)
I also tested this problem by having 2 Imail server talking to each other
on the same LAN through port 1025 (bypassing mcafee webshield),
spamfiltering stopped working again.
(By the way, all other functions of the server works fine on port
1025.)
Anybody has experienced similar problems, or any problems with spam
filtering by using other SMTP port # than 25?
