postfix or qmail?

[Luciano Musacchio]

hi,
I've a simple question, postfix or qmail? :), I've a fair review for both from 
some linux admins, now, I want to know fbsd's community opinion :). The mail 
server (now running sendmail) serves ~300 accounts.

Other thing (perhaps, the one that I interest more your opinion), do anyone 
know why MacOS X Server is using postfix instead of qmail? (i mean, the 
latter is far more popular, right?),

thanks ppl
