Okay, running Exchange 2003 enterprise with SP2. After installing I started
looking around for documentation on IMF and most that I found was about IMF
ver 1. I've also been paying attention to comments on this list and others
about IMF in general.
I have some simple things that I want to do
1) block certain domains (blacklist) at the smtp session level so I don't
have to deal with their crap
2) block certain accounts at the smtp session level that used to exist on the
exchange server. We have several accounts like contact@xxxxxxxxxx and
subscribers@xxxxxxxxxx, that we dumped as they were get 99% spam and 1% real
messages
3) some general blocking at the smtp session level using RBL's and the like
to reduce the amount of spam and viruses that our Trend Client Server
Security Messaging Suite (ver 3.0) needs to deal with.
4) whitelist specific emails and domains, particularly mailing lists used by
the staff, I see from Carl Houseman's comments, this might not be possible in
IMF 2.0
The firewall is the fortigate FG60 which also has the capability to block
incoming smtp traffic, however, it's antispam solution is not granular enough
for my tastes.
So is IMF the tool for me, or are there other free or cheap solutions to do
the trick at the smtp session level?
