But I think there were two steps: 1) During SMTP RCPT TO, check is mail can be delivered via LMTP RCPT TO, 2) actually deliver mail via LMTP. Where 1) failed (except with warn_if_reject), but 2) succeeded? Where both were basically doing the same thing, except I suppose with some actual difference. Or were the mails really not delivered via LMTP but something else?
