Most of the spam messages that I receive are addresses to non-existing users... Mailing list I guess... Can I setup a way to accept mail for only a list of e-mail addresses?
Yes, there are a number of ways to do this. Search the list archives for "md_check_against_smtp_server"
Alas Exchange tends to accept EVERYTHING and send rejects later. With later versions of Exchange there's a registry hack to get it to behave properly.
At one point I was using sendmail / mimedefang / etc in front of an exchange server (and have since gotten rid of the exchange server thankfully) ... at that time I used some sendmail rules to do LDAP lookups into the active directory to determine deliverability of mail and reject if undeliverable.
We were using Exchange 2000 which didn't have the registry setting.
as far as outgoing mail was concerned, the exchange server was on a local subnet (192.168.0.x) and I had the sendmail machine multi-homed.
I just added the IP of the Exchange server into the access database with RELAY and used a mailertable to route incoming mail to the exchange server.
while we were using the exchange server, it worked pretty nicely.
