Migrate mailman/pipermail/lists.openstreetmap.org from shenron

[grischard]

Shenron is our last server at bytemark, and the mailing lists are one of the last services on shenron.

See also:

• Migrate to fafnir for email (Migrate email services from shenron to fafnir #782),
• Migrate to jakelong for discourse (Migrate help.openstreetmap.org from OSQA to static html archive  #149),
• Migrate Bytemark services (Migrate Bytemark services #780)

We are currently running mailman 2.1.29. The latest version of mailman 2 is 2.1.39. The last version of Ubuntu to package mailman 2 was 20.04 - recent ubuntus only include mailman 3, which is a major migration.

Pipermail, the current mailing list archive tool, is written in python 2 and deprecated.

@grischard Would migrating to Mailman 3 solve encoding problems like the ones below?

[tomhughes]

I mean there are probably much easier ways to solve them if you report them.

@tomhughes Done: https://bugs.launchpad.net/mailman/+bug/2088021

I hope I've found the right place for it.

[tomhughes]

NO! I meant report it to us as a separate issue instead of trying to piggyback on this.

Firstly mailman 2 is dead upstream so a report there is pointless and secondly they're not going to care about omebody entering a list description in the wrong encoding - that's just a data issue in the configuration of that list.

@tomhughes I'm so sorry! I've invalidated that report and submitted a new one here: #1179
