I've been working on installing mailman3 in several environments where postfix integration is a bit tricky (mailman server is different from postfix mail server, we're using docker in one case) so the handling of lookup maps via files is a pain. On one installation I had to rsync generated maps from the mailman machine to the mail sever, on the other one I'm still struggling to understand why postfix won't open the NFS-shared files having mode 0660 even though uid matches. So my GSoC proposal is: Provide postfix_domains, postfix_lmtp, postfix_vmap access using the socketmap interface. Socketmap (http://www.postfix.org/socketmap_table.5.html) is one way of providing maps to Postfix without sharing files. Writing a socketmap server should be easy enough but could be very helpful for multi-server setups.

With 2 containers having access to the same shared filesystem (either running on the same docker host, or using a network filesystem when you've got a cluster) it is pretty straightforward. In a configuration where Mailman3 and Postfix are running on separate hosts, I have used the Mailman3 "postmap-command" option in var/etc/postfix-mailman.cfg to call a shell script which first runs postmap and then copies the map to the postfix host. That works well enough, but it took some time experimenting with several options. You need to set the lmtp_host and lmtp_port options in mailman.cfg to point to the container running Mailman3. If you expose the container LMTP port to the docker host, it might be easier, but it's likely safer to keep the inter-container communication really internal. We're currently working on moving our mail system over to a "mailu" dockerized implementation, so I will gather some experience in connecting Mailman3 with a dockerized postfix.

[Mailman-Developers] Re: Working towards a hassle-free Docker deployment
Just to keep anyone looking at this up-to-date: I've settled for option 2 (installing from source) and fixed the separate-host problem by implementing an ersatz postmap script which calls postmap and then uses rsync to copy the files to the mail host: #!/bin/bash # in addition to running postmap, copy the files to our mail server /usr/sbin/postmap $1 rsync -a $1 $1.db mail.heeg.de::postfix-mailman3/ Of course this requires setting up an entry in /etc/rsyncd.conf but then it works reasonably well. The socketmap service is still something I'd like to tackle when I have time.

[Mailman-Developers] Working towards a hassle-free Docker deployment
Hello, due to the need to modernize our Mailman installation, I want to switch two installations to Mailman3. My options currently seem to be: * Install from distro repository (Ubunut 20.04) - they only have Version 3.2.2, which does not play well with the Python version 3.8.2 that's also in the repository :-( * Install from sources - not really difficult, but I fear that regular updating might be a bit of a hassle, and integration into the system as a service needs a bit of manual work :-( * Run the Docker images created by maxking, which would probably be the most painless option for one of the sites, but there's still a caveat :-( One problem which is present in all 3 cases is that the mailman server (or container) is not on the same machine as Postfix. For mail input and output that's not a problem since Mailman speaks LMTP and SMTP, but sharing the Postfix maps between machines is a bit tricky. NFS should theoretically work, but getting all permissions right is not trivial. This is somewhat more pressing in Docker where I don't even have control over the UID running Mailman inside the container. Therefore I would like to add a socketmap service to Mailman that Postfix can query to get map information. Since this idea is probably not totally original I'd like to ask on this list whether someone already tried such a thing, and what their experiences were.

I can't find a way to do this in the current version, and I saw similar functionality being requested on the 'wishlist', so I assume that it has yet to be implemented. It's already mostly there: The command list_owners -m prints all owners and moderators of all mailing lists on your machine. Getting these into a mailing list should not be that hard...
