List-ID and FROM address of the list changed around October 17th

Hi, I just noticed that some of my mail search filters wouldn't apply anymore for this list. It turns out that the List-Id for messages has changed around October the 17th 2022. The list is also sending mails from bird-users@trubka.network.cz while the lists address is the same. Mails received since then have the following List-Id header set: List-Id: Discussion of users of BIRD Internet Routing Daemon <bird-users.trubka.network.cz> It used to be: List-Id: Discussion of users of BIRD Internet Routing Daemon <bird-users.network.cz> Not a huge deal for me just thought it would be worth mentioning in case this isn't intentional.
