The alternative has always been Mailman3, which is the technological successor of Mailman3, but a complete rewrite. As early as its initial release in 2015, I've been eyeballing moving to it. Back then, there was no migration path from 2 to 3, but it was on the roadmap, which made the choice to move or stay easy: wait for the release which makes it possible. A lot of time has gone by since. The situation gradually worsened, because the migration to Mailman3 became a blocker to upgrade the operating system on common-lisp.net: python2.7 was phased out, which means the mailman2 list software wouldn't run on it anymore (that is, without significant maintenance burden to maintain our own python2.7 install). Long story short: Yesterday, I installed the containers which allow us to run mailman3 in an isolated environment. There's a lot of tweaking to be done, but I've been able to configure mailman3 to run alongside of mailman2, which is a good start. As of right now, I've started migrating to mailman3, which I'm doing in steps: - basic validations - archives of defunct lists - active mailman2 lists with configuration and archives Before going the route of migrating active lists, I may do an assessment of the activity of mailing lists, asking owners of mailing lists which have gone without activity for 5 years, whether there's still an active interest.

It took me a bit to understand the error Exim was throwing and the fact that the mailing list software was causing this problem. Another reason to move to Mailman3: it will use a completely different configuration. -- Bye, Erik. http://efficito.com -- Hosted accounting and ERP. Robust and Flexible.
