[03:30:35] <legoktm>	 is there a "Cool URIs don't change" expectation for email addresses?
[03:31:24] <legoktm>	 in https://phabricator.wikimedia.org/T280472 I'm proposing we remove legacy mailman domains so e.g. wikitech-l@(mail\.)?wiki[pm]edia.org will no longer work
[03:31:52] <legoktm>	 given that lists.wm.o was adopted in 2007, I think that's a reasonable amount of time for everyone to update their address books
[03:33:07] <legoktm>	 (I have no idea if those legacy addresses even still work today, but we have config in some places trying to support them)
[07:16:40] <Nemo_bis>	 legoktm: to answer that question we'd need to know what's the relevant resource people usually try to locate.
[07:17:28] <Nemo_bis>	 I'd argue it's usually the mailing list description/archive, so if we still have redirects for HTTP requests to the mail. subdomain the impact of breaking mail delivery is limited.
[17:19:43] <legoktm>	 Nemo_bis: it's a bit confusing, mail.wikipedia.org redirects properly, mail.wikimedia.org does not (T280473). But mostly I want to clean up our exim config and stop accepting mails on those legacy domains
[17:19:46] <stashbot>	 T280473: mail.wikimedia.org doesn't redirect to lists.wikimedia.org - https://phabricator.wikimedia.org/T280473
