Storage location of e-mail received via Mailman

rlenferink

Hello everyone,

I have mailcow + mailman successfully running for some time now (installed using this guide: https://docs.mailcow.email/third_party/mailman3/third_party-mailman3/)

And I am wondering whether someone knows where the e-mails that are received via mailman are stored on disk?

I know mailcow stores the e-mails in the vmail volume with a Maildir for every e-mail address, however I can’t seem to find the storage location for e-mails received via mailman. I assumed they would also need to go through dovecot and therefore in the same vmail directory.

Does anyone know about this?

After some heavy digging I just found that by default no Maildir directory is created and e-mails are only archived through Hyperkitty instead.

To enable the Maildir format (per mailinglist) the following option needs to be added in the mailman-extra.cfg:

[archiver.prototype]
enable: yes

After enabling that option and restarting mailman (+mailcow) the prototype option can be enabled per mailing list (Manage this list -> Settings -> Archiving -> Active archivers).

Downloading an mbox file through Hyperkitty is also possible by using the /export/ url for a mailing list, e.g.:
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/export/file-name.mbox.gz?start=2023-03-01&end=2023-04-01
