Specs are pretty good, may want to add more ram eventually and the storage
should really be at least RAID1 for a server that 4000 people rely on for
email...

What IMAP Server?  I've found this is the biggest performance factor for a
mail server, at least in terms of what the user experiences (i.e. they
rarely notice if an email takes 5 minutes instead of 30 seconds to be
delievered but they definitely notice if it takes 30 seconds to login and
see their INBOX of 3000 messages).  I'd stay away from UW-IMAP at all
costs.  Look into Courier or Cyrus for a reliable, fast IMAP Server.

~1500 fac/staff and students for a small university.  We're running
Courier and Squirrelmail on a 1.5ghz P4, 768mb ram, 40gb IDE RAID1.  Not
the best specs for a server but it runs like a champ.

Courier and Squirrelmail have proven to be quite stable.  Not to many
issues.  Do some testing before opening it up to 4000 people (maybe a beta
group?), Keep good backups, use the server regularly yourself to keep an
eye out for performance issues or problems.
