We've recently migrated our project's email lists from mailman2 to mailman3. Given the project has been around for a few decades, many people have used different email addresesses over the years, some of which they no longer have access to. However, it would be useful to still be able to associate those emails with a given account. Is there a way that I can do this as an administrator of the mailman3 system?
You can certainly add extra addresses to a Mailman 3 user (I don't know offhand whether/how an admin can do it through Postorius, but the core database certainly has that facility and the REST API allows it).
However, this doesn't have the same semantics as in Mailman 2 because Mailman 2 doesn't have users at all. So as an admin how do you know which addresses correspond to particular users? More generally, what do you mean by "associate with an account", and why do you want to do it?
Normally I would not ask the latter question, it's your business why you want to do it. But here I'm trying to get at what semantics you want. If I were going to do this for the kind of purposes I can imagine, it would be a matter of informing the users that this feature is available, and I'd ask the users to do it if they care. It seems you have some project goal in mind though.
