I think you got some good comments about this part already.

I do think that smail is generally easier to configure than sendmail, but
it is also less flexible.  That can be a problem, and although I've run
both smail and sendmail I've usually ended up switching back to sendmail. 
You should also consider that sendmail is the older of these programs, and
is almost certainly the most common mail transport agent.  Sendmail has
had its share of security problems, but part of this may simply be due to
its ubiquitous nature.  If security and speed are of prime concern to you
I'd suggest that you check out qmail <http://www.qmail.org/>.
