this is going to depend on how busy the server will be.
how many emails per hour are you expecting people to
receive (legitimate and spam/virus/backscatter) and send?
how much IMAP activity? how big are their mailboxes going
to be? how much CPU time will you need to spend on
antispam and antivirus filtering? once you know all that
you can estimate the demands on the disk subsystem and on
CPU and memory.

or you could just buy the cheapest machine you think won't
get you laughed out of the data center, and then buy a
bigger one when it proves inadequate.
