Basic kind of question

I inherited a pair of postfix servers configured by someone else and I think I've been a manager too long as I can't figure this one out because I'm too rusty with postfix. Scenario: 2 identical postfix servers that only accept mail from mynetworks (other local servers in its /16) with various

New SASL generic failure

Working system that suddenly started crapping out on SASL-authenticated connections to its relay. Nothing's changed for this 2.11.0 Apple-supplied postfix, and the username/password authenticates fine to smtp.comcast.com (relay). I'm not see what's wrong (must be what "generic" means lol).

One more post-rebuild weirdness

OS X Postfix system rebuilt as a relay with no local mailboxes, but we're not passing inbound mail to the final destination except for the few people who have local accounts on the postfix server. Soft bounce is onluckily (great safety net, Wietse). I have something that's negating
