When I get these on v6ops, which happens from time to time, it usually means
that there has been an email in queue that has timed out or otherwise been
found undeliverable. The single most common situation is that the recipient is
in China; draw your own conclusions.
My gut tells me that the issue is political with technical ramifications.

Dear IETF email team
(As ANIMA WG chair) i just received 31 emails of the type
Date: Wed, 18 May 2022 09:00:01 -0700
Subject: Anima unsubscribe notification
someone(_at_)example(_dot_)com has been removed from Anima. (disabled
I don't remember i have seen this before over the years. If this is a new
and there was an email explaining it, i must have missed the email or URL
explaining it. Pointer welcome.
This looks like a nice feature to eliminate old junk, except that i am worried
(after the recent incident with my own emails spam filter caused
how exactly the condition "disabled address" is determined.
In general, i am not a big fan of what is probably intended as a user-friendly
explanation such as "disabled address" without also providing the actual
root cause diagnostic. It ony gives me "Admiral Failure" frustration.
When i sent an email to one of the addresses i did know to be obsolete,
SMTP gave me:
<someone(_at_)somewhere(_dot_)com>: host mx5.somewhere.com[1xx.xx.xx.xxx]
5.1.1 <someone(_at_)somewhere(_dot_)com>: Recipient address rejected:
recipient validation check.: host 127.0.0.1[127.0.0.1] said: 554 5.7.1
recipient verify from ldap failed (in reply to RCPT TO command) (in reply
to RCPT TO command)
I would appreciate if this error indication would also be included in the
"Unsubscribe notification" email, so that we as WG chairs (or other mailing
list owners) can do our best to help finding false positives.
