Mailman2 migration to Mailman3

[bonomani]

Decision

• Migrate to JC VM
• Supported by JC with the help of Henrik

Migration info

• Smooth and quick transition as much as possible
• Possible outage during the migration (dns entry sync)

Goal of the future solution (to be reviewed)

• Secure the archives (backup like 321)
• Ensure an admin (diversity)
• Be documented

Current Plan: Migration to Mailman 3

• [x] Access to Henrik Mailman 2: (Action: JC, Date: Asap)
• [x] Prepare/install Mailman3 software: (Action: JC, Date: ASAP)
• [ ] Migrate data from mailman2 to mailman3 with the archives (Action: JC, Date: ASAP)
• [ ] Migrate DNS entry (Action: Henrik & JC, Date: ASAP)
• [ ] Review if goals are reached
• [ ] Document
  • Components
    • The software itself (ans it component)
    • Dependencies: DNS, Mailboxes/redirect?
    • The server
    • The backup
  • Administrative info
  • Who manage each component
  • Diversity
  • How it works

Info

(Need probably to be completed)

• Dead line of the migration: beginning 2024
• Email address used: xymon@xymon.com
• domain xymon.com own by Henrik
  • lists.xymon.com subdomain pointing at xymon.com
• Mail Server: mx.hswn.dk
• Other Xymon mailing lists/archives exists on Sourceforge
• Mailman3 is the natural mailman2 (current) successor
  • Allow to to keep the archives (lot of information that need to be kept)
  • Migration should not be too difficult
  • Other solution exists that are more "modern" and "attractive" solution" but not so "simple" if we want to keep the archive
• Mailman3 Hosting Solution
  • Requirement
  • Mailman3 requirements (mandatory)
  • Xymon.com domain (mandatory is presume)
  • Mailboxes (mandatory/optional?)
    • Redirect ?
  • Admin diversity (optional but desirable)
  • https://mailman3.com/
  • Free service for open-source projects: https://mailman3.com/ Really Free ? Ads free ?
  • Limitation:
    • No custom domains feature, only under @mailman3.com
    • 5 Lists
  • To have xymon.com lists costs 150 EUR for a year
  • Do not provide mailboxes, only email redirect!
  • Free solution do not really met requirements
  • Investigations stopped
  • Not free, but quite cheap: https://www.mailmanlists.net, https://www.a2hosting.com/mailman-hosting/
  • A hosting solution list: https://wiki.list.org/COM/Mailman hosting services

People that can help (but not limited to this people)

Torsten Richter:
I am using Xymon now for some time and also benefited from the list a couple of times.
I also have a small mailing list running on one of my servers for private stuff 
which I recently upgraded from mailman 2 to mailman 3.
I would be delighted if I can be of any help here.

Corentin Labbe:
If nobody want to do it, I could try to install a mailman on my personnal server.
The list is so low traffic that should not be a problem.

Latest news: 27.01.2024 JC: WRT the mailing list, mailman3 is (finally!) fully available on EL9 -- including the web interface needed for signups -- so hoping to complete the transition to the new server shortly. Just has been a very busy last two weeks.

Thanks for the poke. This is something I might be able to work on later on today, Pacific.
