[ietf-822] IETF mail server blacklisted by (was: I hate mail these days (was: Re: Deine Mail ist kaputt))

General question: Whats the right mailing list for discuss/problem like this

Disclaimer: I really hate mail these days.
[  First it is rejecting a lot of mails, punishing valid senders

In any case... What's next ? Do i need to click on the "Remove from list"
button there, or does this occurance justify a more basic reaction, such
as checking the IETF mailing list subscriptions against honeytrap domains ?

And... whats my best (least overhead) action to ensure my email subscription 
gets re-enabled
on all the IETF mailing lists where it may get disabled because of rejecting
emails from IETF mailing list server... ?
