Most of the discusion has been about what should be the default.  For "newbies"
sendmail can be a pain to configure.  It's documentation leaves something to be
desired, and the default sendmail.cf file isn't all that helpful.

That's not to say that sendmail isn't useful or does't work properly.  It does.
But if a package is going to be the default for a distribution, it should also
be fairly simple for new users to configure and adapt to.

I haven't looked at postfix yet (will tonight maybe), but for exim all one has
to do is uncomment one line in the default config file once spamassassin and a
virus checker are installed.  Very easy.
