Oops, I have totally forgotten one thing.

For 2000 students and faculty (well, I guess faculty may or may not be 
hosted on the same box but even if it is a different domain, it is not 
hard) and the constant yearly addition and possibly removal of accounts, 
I would suggest a system where the user information are stored in a 
database (mysql) and virtual mail storage (only one system account is 
used for all email account mailboxes).

This is possible with postfix alone, you just have to work out the 
database schema yourself and build the interfaces needed for 
addition/removal of email accounts otherwise you will or whoever will 
have to do all that manual by running sql statements.

With qmail, you can add vpopmail and vqadmin which does all the above 
with the additional plus of having spamassassin support for mysql vpopmail.
