I had postfix working good before the buildworld, now it doesn't work at all. If you use sendmail and do a buildworld, sendmail works fine afterwards but not postfix. I went back and setup postfix like I did before and for some reason it won't start. Dunno what happend, I guess I should just stay with sendmail.

A couple of questions.

I read that postfix was more secure than sendmail, is this true?

Anyone knows about Exim and Qmail? I've never tried those, are they any good?

If you use Exim or Qmail will they get hosed during a buildworld like postfix?

TIA
