However, it is required that Mailman has a (sub)domain +respectively a namespace on its own. A helper script called ``qmail-lmtp`` is +needed and can be found in the ``contrib/`` directory of the Mailman source +tree and assumed to be on ``$PATH`` here. + +As qmail puts every namespace in the address, we have to filter it out again. +If your main domain is ``example.com`` and you assign ``lists.example.com`` to +the user ``mailman``, qmail will give you the destination address +``mailman-s...@lists.example.com`` while it should actually be +``s...@lists.example.com``. The second argument to ``qmail-lmtp`` defines +how many parts (separated by dashes) to filter out. The first argument +specifies the LMTP port of mailman. Long story short, as user mailman: +:: + + % chmod +t "$HOME" + % echo '|qmail-lmtp 1 8042' > .qmail # put appropriate values here + % ln -sf .qmail .qmail-default + % chmod -t "$HOME" + +.. _qmail: https://cr.yp.to/qmail.html +.. _djb: https://cr.yp.to + + Sendmail ======== View it on GitLab: https://gitlab.com/mailman/mailman/compare/6a8cbd3b1f3fb7f3806eadb131700091d32a31b4...a33cf78968fd73651054b0159f92e21a0aa6da61
