I have a Mailman 3 email list, running on Mailman 3.3.3 on Debian 11.
A few of the list members are reporting that they received Email Address Unsubscription Confirmation emails, but claim that they never requested to be unsubscribed. (All are Gmail users. but they might be coincidental, since most list members are Gmail users.)
Has anyone seen this behavior before? Any ideas on what might be happening?
Yes. This is someone sending an email leave or unsubscribe command
for the user in question. This may be malicious, i.e. someone doesn't
like a user's posts and tries to unsubscribe them, or it may be just
spam of some sort.
the user should just ignore the email. Beyond that, there's not much you can do unless you can identify from mail logs the source of the requests.
