mail server recommendations?

[Bob Martin]

If you want something quick, easy and commercial, have a look at 
surgemail from netwinsite.com. Has everything you want, and is very 
reasonably priced. ($770.00 US for unlimited users) It won't scale well 
~10k users per box (YMMV depending on hardware), but it can be 
clustered. Whole thing can be configured and running in under an hour. 
You get a really nice webmail interface, and the ability to "delegate" 
control. Very nice if you don't want to manage hosted domains.

For open source solutions, we've had killer results with 
postfix/amavisd-new/spamassassin/f-prot, courier-imap and teapop. All 
can be used with a number of db's, from berkeley to oracle. We have one 
corporate client comfortably running this config on P3 1ghz with 256mb 
of RAM. The ~18,000 users are controled by SAP (SAP has a FreeBSD client 
for DB access)

I noticed Communigate mentioned in this thread. It's a killer product, 
but too expensive. They don't lie when they say it scales well. One of 
the installs we've done has 9,000 users on a K6 2 500...
