    For what it's worth, this is what happened on a Postfix 2.3.7 server here:

    Nov 1 12:01:25 smtp0 postfix/cleanup[22186]: D8A041BF4E9:
    message-id=<>
     Nov 1 12:01:26 smtp0 postfix/qmgr[24395]: D8A041BF4E9:
    from=<>, size=608, nrcpt=1 (queue active)
     Nov 1 12:01:26 smtp0 postfix/smtp[22501]: CA4461BF34D:
    to=<>, relay=127.0.0.1[127.0.0.1]:10024,
    delay=0.38, delays=0.22/0/0.04/0.12, dsn=2.0.0, status=sent (250 2.0.0
    Ok: queued as D8A041BF4E9)
    Nov 1 12:01:26 smtp0 postfix/smtp[20323]: connect to
    avt0.mail.griffin.com[85.189.39.40]: Connection refused (port 25)
     Nov 1 12:01:51 smtp0 postfix/smtp[20323]: D8A041BF4E9:
    to=<>, relay=av.griffin.com[85.189.39.7]:25,
    delay=26, delays=0.12/0/9.4/16, dsn=5.0.0, status=bounced (host
    av.griffin.com[85.189.39.7] said: 554 <>:
    Recipient address rejected: Access denied (in reply to RCPT TO command))
     Nov 1 12:02:08 smtp0 postfix/bounce[22655]: D8A041BF4E9: sender
    non-delivery notification: 9A9AA1BF515
     Nov 1 12:02:08 smtp0 postfix/qmgr[24395]: D8A041BF4E9: removed

    Which all seems to be as expected, except for maybe the 26 second delay.
    Could have been something going on on my server though, I suppose. The
    extra loop in there is the message going through clamsmtpd, FYI.
