Hi, How would this be done? I assume take Mailman2 down for a day or 2, standup Mailman3 and migrate the lists but this seems a high risk undertaking. regards Steven

Off-topic: Microsoft SNDS seems to have moved or disappeared, can anyone help?
by Jayson Smith June 15, 2026

Hi, In the past whenever I had a problem with my IP being put on Microsoft's infamous internal blocklist, I used the resources at their SNDS sender support site to get it fixed. I had a script which used a URL containing my API key so I could check that my IP wasn't on their blocklist without having to go to their site. This is important because although I've spun down my Mailman installation, I still send about eight messages a year to over 400 subscribers as part of a non-Mailman mailing list. A few days ago I noticed that SNDS doesn't seem to be where it used to be, it just points to the new Microsoft Postmaster site. Even their own links to SNDS on their support pages within this new site seem to go to the same place. Does anyone have any idea what they've done, what's going on, etc? Thanks, Jayson

DreamHost ending discussion lists
by Michael Welch June 7, 2026

Mailman friends. We just got the horrible news that DreamHost is going to axe all discussion lists in about 2 months -- no more Mailman. They just sent an email announcing this. Our account at DreamHost is a free nonprofit account, been using their Mailman service since 2008. We have several Mailman 2.1.39 lists there, two of which are extremely important technical lists for solar installers across the nation. We could use some suggestions on new hosts for the Mailman lists. Preferably no- to low-cost to our nonprofit organization. And we will need some help migrating the lists and Pipermail archives to a new site. And possibly an upgrade to Mailman 3. Any suggestions / help will be greatly appreciated.
