FAQ
Hi there,

We use Mailman 2.1 with Qmail and Plesk (v10.2). Everything works nicely
with Mailman however it's not sending out the bounce emails to the owner
to say there are pending requests. Upon checking the
/var/log/mailman/smtp-failure logs, it's showing that
website-owner at website.name doesn't exist when mailman tries to send the
bounce request to the list owner. It does however send back the user who
sent the email a pending request saying that their email is awaiting
authorization. There's all the .qmail files in
/var/qmail/mailnames/website/.qmail-listname-* and have this type of format:
/var/qmail/bin/preline /usr/lib/plesk-9.0/mm_wrapper
/usr/lib/mailman/mail/mailman owner websitename

If I try and send an email directly to website-owner at website.name, it'll
bounce back straight away with:
550 sorry, no mailbox here by that name. (#5.7.17)

It's like qmail isn't passing control to mailman when doing recipient
verification? Has anyone else had these issues with Plesk and Qmail?

Cheers, Mike

    "Bounce" is a term of art; it means "mail returned because it was
    undeliverable". Mailman doesn't send out bounces to anybody, although
    it may forward bounces it has received from MTAs to list owners.

    The messages you are referring to are notifications of pending
    moderation.

    It's important to keep these separate because bounce processing is an
    extremely important (and complex!) part of Mailman functionality, but
    it is completely separate from the moderation queue.

    website-owner at website.name doesn't exist when mailman tries to send
    the bounce request to the list owner.
    Evidently, Mailman has been configured to send to a non-existent
    address. (See the 2d and 3d items on the General Options page,
    assuming Plesk hasn't mangled it.) There is not enough information to
    speculate on how this happened, but it's not a Mailman problem.

    To solve it, somebody needs to get real addresses of the mailing list
    owners, and either configure Mailman to send to them directly, or to
    set up aliases to website-owner at website.name for them in qmail so the
    that the pre-configured addresses work. It's possible that Plesk
    offers a front-end that is supposed to handle this in a convenient
    way, but if that's failing, it's a Plesk problem.
    It's like qmail isn't passing control to mailman when doing recipient

    Mailman doesn't, and can't, verify addresses; it can only ask qmail to
    try to send to the addresses that admins and subscribers have
    registered with it.

    The specific qmail alias you quote above looks wrong. I would expect
    something more like
    /var/qmail/bin/preline /usr/lib/mailman/mail/mailman owner websitename or
    /var/qmail/bin/preline /usr/lib/plesk-9.0/mm_wrapper owner websitename

    Look at the /var/qmail/mailnames/website/.qmail-listname file. The
    /var/qmail/mailnames/website/.qmail-listname-owner file should have
    exactly the same ownership and permissions and should have exactly the
    same contents except where
    /var/qmail/mailnames/website/.qmail-listname has 'post',
    /var/qmail/mailnames/website/.qmail-listname-owner should have 'owner'
    (and similarly for the other
    /var/qmail/mailnames/website/.qmail-listname-* files).
