It's a weird situation. Like I told Kunal: I've never had problems before, only after the upgrade and only for checkuser-l.

I was afk for a few days, and only now I noticed my email got disabled again on 1 June. So I missed quite a few emails. As checkuser-l isn't archived I can't read them back (only when someone emails me the missing emails...). I think we should do something about this on our part. I don't think the problem is my email. Perhaps Hotmail as a whole?

Onderwerp: Re: [List admins] Subscription disabled due to a bounce score?

I was just notified of 25 unsubscriptions from the Wikidata mailing list
(and 2 on WikiIT-l). They were probably all "real" bounces, and mostly
they were former WMF or WMDE staffers whose mailbox was presumably
disabled, but I saw some addresses that I know for sure are working.

Google, Microsoft and others are known to lie about mail delivery. It's
possible that by sending an unusual amount (or rate) of email to some
non-existing addresses we got somehow treated like spammers, and some
messages to existing mailboxes were treated as the kind of spam that is
bad enough to bounce back with a lie but not bad enough to be silently
discarded. I have no idea how to debug this for Google or Microsoft
mailservers but I've suggested one user whose email is on a personal
domain name to file a bug with any logs they might have. I hope that's fine.
