Hi, I'm using mailman (stable 2.1.33) for several mailing lists.
Since there seems to be only a Python 2.7 version, mailman is now masked and will soon be removed from the tree. I have already copied the mailman ebuild to a local overlay, but that's surely not the best idea in the long run. What would the best (and simplest) solution to port the existing mailman mailing lists to another mailing list system (perhaps even with full-/half-automatic transfer of e-mail-addresses, greeting and farewell messages and all that)? Which one would you recommend? Googling for "Alternatives to Mailman" found several programs - the only one of them with a Gentoo ebuild seems to be "mlmmj". Would porting the mailman data to mlmmj be easy or difficult? On the other hand, there seems to be a mailman 3 version (which is not yet in the portage tree), but I could install it manually of course (though that sounds pretty complicated?!), and there are some update docs at https://docs.mailman3.org/en/latest/migration.html and there is a simple "mailman import21" command for importing the data of the old version. Would that be better/easier than to switch to a completely other system (even if the new mailman 3 would not be administered by portage)? Any suggestions how to proceed? Many thanks in advance, -Matt
