Just to make it clear to the OP, I have a Dovecot/Sendmail/SASL working
just fine (which is independent of dovecot).  I suspect Peter hit the
nail on the head here.  Look at the contents of


Mine is (only)


which I think looks up my name service backend via the login and plain
plugins.  I'm a little hazy on how this was set up, but if you are able
to successfully login without dovecot, then it appears you have some
sort of authentication stack that will try IMAP first, then fallback
to your the other method.
