It depends on how customized your sendmail installation is. Postfix
will read the old /etc/aliases without any trouble. If you've done a
lot of tinkering with sendmail.cf it may take some time to get postfix
configured exactly the same way.
As far as security goes, Venema also wrote tcpwrappers, so he knows his
security. As for whether it's the best security wise, I don't feel
qualified to judge it. Certainly it is better than sendmail was, but I
haven't used sendmail in years so I can't really compare it to the
Postfix and qmail were both written with security as a goal from the
beginning. qmail's license is a bit more hassle (last time I checked
you aren't permitted to distribute binary packages without Bernstein's
consent) and frankly I personally find postfix to be a lot easier to
configure than qmail (you are in a maze of .qmail-* files, all alike).
I've been extremely happy with postfix.
