My operation have just the most superficial resemblance of a  "company"
(it's years since I earned any money out of it), but the setup I have is
sendfail+spamd on one box and dovecot on another, that works far better
than I've ever dreamt of.

Security: at least not much worse than the alternatives
 - Only stuuf in "base" + dovecot (which hasn't been laughed at
   too much security-wise, and it's got a security stance)
Ease of setup: Quite.
 - Dovecot is in ports (v1.0.0 checked in yesterday)
 - The version I believe is in 4.1 (1.0.rc22) is the one I run
   (from a late february snapshot) hasn't failed me at all
   (but see the errata at http://dovecot.org/oldnews.html)
 - sendfail setup has never been easier than with the
   exquisite OpenBSD documentation
 - ditto spamd
Scalability: I think so, but I might have fallen prey to a
certail nevel of hype. Especially Dovecot seems to have
a good track record.

I don't know much about ease of use by end users. I
find it easy but I don't think I'm typical. My few users
(mainly in the family) asked me to set their mail up,
but I do have the users I deserve...
