I have been a UNIX geek for quite a few years and in that time I have had
the pleasure or displeasure of working with many mail packages. The 2 that
I had the most exposure to was Sendmail and Qmail. Now barring any flames
about sendmail, once I had exposure to Qmail I will never turned back.
Qmail was developed with security in mind, it has never had a security bug
in the years it has been available, it is scalable, reliable and easy to
administrate. Now I will not bore you with every spec or detail about how
it runs but even Hotmail.com uses Qmail as it's MTA. This the one of the
leading webmail sites in the world with between 80-100million accounts, and
still running strong. I would definitely put my vote to Qmail for any
organization, any size!

Qmail doesn't scale well with large injection rates. Qmail scaling in that sort of manner is completely dependant upon the filesystem. Now this may have changed, but not that long back everything in submission was in one dir, processing in another dir, just like sendmail (by default) does. This caused the queue manager to stuff up something wicked at high injection rates.
