You can turn off recordio for this test.

I'm not seeing a doubling up that could happen if two internal processes both write the email into Maildir.  I'm seeing 4x deliveries for a single email in the /var/log/qmail/smtp/current logfile.

I've upgraded my qmail version today, and will run more tests to get the clean capture that Eric has asked for.

    I've noticed this too
    Could there be a bug in qmailadmin / mailfilter here

    By default there is no .qmail in a users folder and editing the
    account does not create one .. but qmailadmin does maintain it.

    if you install dspam

        https://raw.githubusercontent.com/qmtoaster/dspam/


    it creates the .qmail as a result

        |/var/qmail/bin/preline /usr/bin/maildrop -A 'Content-Filter:
        maildrop-toaster' /etc/mail/mailfilter


    if you then edit the account

        |/var/qmail/bin/preline /usr/bin/maildrop -A 'Content-Filter:
        maildrop-toaster' /etc/mail/mailfilter
        /home/vpopmail/domains/brayworth.com/[user]/Maildir/
        <http://brayworth.com/%5Buser%5D/Maildir/>


    which results in a double up of delivery ...

        is that the two repeats I've had recently were both from

            It's be nice to have the smtp log and the email header.

                Hi Chris,

                Did you save any of the SMTP logs for those messages
                that were re-delivered and email headers?

                        A few nights ago I shut down the VM
                        that my qmailtoaster runs on, bumped
                        the memory up to 4g, and restarted it.
                        First reboot in a long while, so I was
                        nervous. Everything seemed fine.

                        The next day I noticed that there were
                        a couple of emails I had deleted that
                        had re-appeared. I'd delete them again,
                        and they'd come back again.  My mail
                        client shows date sent and date
                        received, and they were definitely all
                        the same sender time. Checking the
                        logs, I see the same set of email being
                        re-accepted in
                        /var/log/qmail/smtp/current over and over.

                        Finally I have a clue. Gmail sent me a
                        delivery warning about one of the
                        emails, as it was a test message from
                        myself, and it says my server is
                        responding with error:

                        421 Timeout. Talk faster next time.

                        So it seems the email is getting
                        accepted, but then the sending server
                        is given an error 421, so it queues it
                        up for re-delivery.

                        Any suggestions on what I should be
                        looking at to figure this out?
