Correct.  This can be *really* annoying if you need multiple services that
need to be configured the same way.  And AFAIK, Cyrus really dislikes it if
you define two services with the same name.

Yes.

Worse, it may actually change how the preauthorization is done. I'd need to
check. Preauthorized just means that if you do nothing, it came from
"postman".  In particular, if you send a different auth through LMTP, Cyrus
is supposed to verify and use the new auth, and DENY the delivery if the
auth is wrong, or does not have the proper ACLs to actually deliver, etc.

I am not sure expceptions do not exist.

If it is not there yet, I agree it is needed.

I don't know about how Cyrus IMAP and SASL are behaving re. allowplaintext,
though, so I won't comment on those (I don't have the time to research that
in the source code right now, sorry).
