  • manually bounce a queued message

    From Marco Moock@21:1/5 to All on Thu Mar 27 21:44:19 2025
    Hello!

    Is there a way to manually bounce a message that stucks in queue due to unreachable MX host (that won't come back, as domain is parked)?

    kind regards

    Yes.


    sendmail -O Timeout.queuereturn=1s -qR$DOMAIN

    or something like that.

    You could also try to "route" the domain to an error,
    see cf/README: mailertable.

    Theres qtool.pl in the contrib directory of the sendmail source tarball.
    Works nice for me.

    Been there, done that.

    A local computer magazine (MBnet) with a quite popular free email system dropped all email services (and the MX records), but kept their website
    (which now just redirects to their current magazine name Mikrobitti).

    All mail queued to them would stay in queue for five days waiting to
    be delivered (to their web server), and only then bounce. I included
    an entry for their domain into the mailertable with error:nouser 550
    so attempts at sending email get bounced immediately.

    They could use the Null MX record.

    They could have, but they didn't. I suspect business decision was just to
    "get rid of the email" and anything else (even removing MX) was extra.

    I'd also add an empty SPF to designate no emails will be sent
    "v=spf1 -all" and empty DMARC "v=DMARC1; p=reject; aspf=s; adkim=s;"
