Re: on smtp filtering...

We currently use a Sendmail replacement called Postifix and then a open
source product called SpamAssassin to pre-process our email stream before it
goes to our lotus cc:Mail server.  www.spamassassin.org.  I'd say that
Spamassassin has been about 95-97% effective in our environment at capturing
spam.

Just be aware that no product will keep all the spam out.  Period.  As the
spam filters evolve, so do the spammer's tricks that are used to get around
filters.

what type of mail server do you use? we currently use sendmail and it
does a very effective job of blocking spammers. most emails servers have a
"hook" (for lack of a better term) that you can use to compare against open
relays. sendmail also lets us block from domains and users. most email
servers have this feature, or very similar, built in. i have not needed to
use our isa server for this purpose.
