There's a bit in LWQ:
http://www.lifewithqmail.org/lwq.html#comparison
Which includes a link to Cameron Laird's MTA comparison, which
includes links to his profiles of qmail and Postfix. The table in LWQ
is a little outdated.
In a rigorous benchmark conducted a couple years ago, qmail beat
Postfix, but both were head-and-shoulders above everything else.
Securitywise, I give the edge to qmail because its
compartmentalization is better, because of Dan's generally bug-free
code, avoidance of the standard C library, and because qmail is much
smaller.
In reliability, qmail again has the edge simply because Dan's code has
fewer bugs than Wietse's.
Configuration is pretty much a draw. Some people like qmail's style
(separate file for each setting) vs Postfix's (lots of settings in one
or more files), or vice versa.
Postfix is easier to drop into a Sendmail system because it handles
/etc/aliases and .forward's out of the box.
Postfix is truly Open Source.
qmail has some innovative features like extension addresses, address
wildcarding, user-managed lists, and user-managed virtual domains that
Postfix doesn't. Postfix has limited extension addresses, but no
wildcarding, if I remember correctly.
Postfix does multiple RCPT deliveries and implements per-host
concurrency limits.
