The best Anti spam - Anti virus email solution

[Brent Bailey]

Hello,
Im looking for you thoughts and opinions on Anti -Spam and Anti virus
solutions for email servers. Im getting ready to implement a email server
solution for an ISP. Im very use to sendmail  as ive been able to compile
sendmail to do rbl checks and use access.db and procmail filtering and
spamassassin
and it seems to work pretty good..although there does seem to be a small
amount of  "false positives" I suppose this is going to happen to some
extent.
So im looking to this mailing list to get your opinions and thoughts on
this. Im more than open to the idea of useing something other than
sendmail :-)
