The drawback to smap's anti-relay and anti-spam features is that
they are limited. That and the fact that the code has such a small
user-base, few contributors, no discussion list, and is not being
actively maintained. Patches in particular are subject to little
or no code review.

Postfix's smtpd is essentially smap on steroids. All the security
advantages plus several additional features (whitelists, header
checks, message size limits, various rate limits, recipient checks,
...). See the mailing list and smtpd man page for details.

Smap does something that Postifx doesn't? What would that be?
