The realistic, well-supported choices other than sendmail are:

qmail (www.qmail.org, cr.yp.to, www.lifewithqmail.org)
Pros: easy to configure, very secure, fairly powerful
Cons: the author is highly opinionated

postfix (www.postfix.org
Pros: easy to configure, reasonably secure, extensible, widely used
Cons: more likely than qmail to have a security problem (but quickly
patched)

exim (www.exim.org)
Pros: reasonably secure, many many options
Cons: creeping featurism

Courier's IMAP is a good choice to use with qmail. I've never seen 
anyone use the full Courier mailserver.
