I don't think what I did will help you, but just in case someone comes 
across this thread, I'll describe my setup. I have to tell up from it is 
laborious. On the other hand, I like what I did.

I set up components I will describe below in FreeBSD jails, a few in 
each jail. There are some that just have to be in the same jail. But the 
smaller the number of components per jail, the more secure in general 
the whole thing will ultimately be. Several components are even living 
in jails with different IP than others.

mail itself: dovecot + pigeonhole; postfix

shell jail (yes, I do give people the ability to ssh to the "server")

web jail (and there there are user web directories, r/w for owner in 
shell jail, readable to apache, no local user in shell jail can read 
other users we directories; through web server only)

webmail with squirrelmail and roundcube

maia for spam filtering - great as it provides per user preferences, web 
interface, laborious for sysadmin though; clamav for virus detection; 
and some distributed spam databases

databases run separately; postgresql for settings of some of the above; 
mysql for maia as storage backend, alas, I never managed to have 
postgresql work here... should be something too mysql specific in maia 
backend storage part.

There is also mail list server, but I mention it separately, mostly 
because I am going to migrate away from mailman 2, so this will change.


I hope, this helps someone.
