I largely agree with this but I've heard so many different sendmail
problems recounted so many times that, while it's not necessarily a
"bad" MTA, I suspect there are usually better options. People complain
about sendmail for being "bloated", difficult to configure, slow,
resource-hogging, and insecure. The only real advantage I've heard is
that it is very flexible/powerful. Calling it "bad" outright would
probably be an overstatement but I think it's worth considering and
evaluation the alternatives.

Qmail was also written with security in mind but Postfix will work
better in terms of being compatible with sendmail-oriented systems. I
also think Postfix has a better license. My own experience with Postfix
suggests that it works really well: it's configuration architecture is
designed with simplicity in mind but it can still probably do pretty
much anything most people would want. It's fast, runs nicely and has
some neat features. I don't think it has as many features as sendmail
or even qmail but I haven't come across any real limitations yet. I
would recommend it to anyone who doesn't absolutely need a unique
feature of either qmail or sendmail.
