Seems I've found that dovecot is handling the auth for smtp, and it doesn't like sendmail very much since their documentation avoids sendmail like the plague.
The Dovecot developer is a smart dude. :-)
None of that makes any sense. Dovecot should have nothing to do with smtp, so of course it doesn't have anything about sendmail in its documentation other than adding its local delivery agent which should be their only interaction and you probably don't even need to use that.
Actually it might. Dovecot can do the sasl auth part. I have not touched sendmail in at least 10 years, so I do not know anything about the current default sendmail config but I know dovecot sasl auth is easier to config for postfix (5 lines in the postfix main.cf IIRC).
I suppose it is possible that RH switched sendmail to user dovecot sasl in their default config.
Sendmail is infinitely configurable, but I don't see any uncommented Auth schemes in the stock sendmail.mc and the smtp-sendmail file in pam.d just invokes 'system-auth' on 5.x and 'password-auth' on 6.x, like most of the other things. Something else must be going on here.
