If that is your only reason for changing, I'd recommend looking
at sendmail+MimeDefang first (http://www.mimedefang.org/).
MimeDefang runs via the milter interface and can do any kind
of checks you want with the results available to sendmail
during the SMTP conversation so you can reject at the smtp
level instead of having to construct and return bounces.
There is a fairly active mail list for support too.
