System-auth was normal in 5.x, 6.x should have password-auth in most or all of the same places. And since you mentioned something about pam_stack earlier, that might be from 3.x, replaced by proper 'include' now. > Correct again.

A yum-installed sendmail should be 'standard enough' if you haven't done something like dropping a Centos 3.x sendmail.mc on top of the new one. > Looks like I'm going to have to push postfix into service.

There might be a little safety-in-numbers from other people who don't know how to configure sendmail, but that's not really a good reason to switch. If sendmail auth works the way you expect before installing dovecot, just rpm -q --list dovecot and figure out which piece is breaking things. -- Les Mikesell lesmikesell at gmail.com
