Hello,
I noticed that I have lost the ability to email wikitech-l, instead receiving an email bounce. @Aklapper suggested that I open a ticket here about it. Is it possible wikimedia side to whitelist an email address? This is a new problem and I really don't want to open yet another email address if I don't have to (been using @ mail.com for wiki since 2017 and am the owner of dozens of email addresses over the years).
