How many, and what sort of load?

Exim is perfectly capable as a mail server. Other good choices
are Postfix and qmail.

Similarly, SpamAssassin and ClamAV are good choices. You'll want
to add an RBL lookup or two --  sbl-xbl.spamhaus.org and dnsbl.njabl.org
are fairly conservative choices.

If you like imp, by all means continue.

The most flexible means of storing email these days is in
Maildirs. Exim, Postfix and qmail all understand them. It will
slightly constrain your choice of IMAP server, but not much.

There are good mailing lists to provide support for all these
packages, and probably local contractors available with
experience in most of them.
