GNOME Bugzilla – Bug 768744
Access to Mailman logs to investigate users who claim to have been unsubscribed from evolution-list@ without knowledge

[Not sure if this is really a bug report, but it seems to be the preferred contact method for mailing list issues]. I am a moderator for the Evolution list on mail.gnome.org. We have recently had an issue raised by a user who claims that he was unsubscribed from the list without his knowledge. He only found out on receiving a confirmation mail from Mailman. This is the second time the same user has had this problem, the first time being in January 2016. Is there a way to allow moderators to see Mailman logs, particularly those pertaining to subscribe and unsubscribe actions? It would be useful to know when these actions occurred and from what IP address they originated, even if only to inform the user that they came from his own machine. Are there any outstanding Mailman bugs which could explain this, or a Mailman server or database outage which could somehow have caused these incidents?
Can you please send me the e-mail address for the user in question? Please use gnome-sysadmin@gnome.org.
The problem was related to multiple bounces being received from the mentioned addresses. What I'd suggest would be giving [1] a look and eventually increase the bounce score to more than 3.0 (which equivs to 3 bounced e-mails as it increments by one at each bounce).

Unfortunately the only countermeasures are a) rewriting From addresses when DMARC-enabled domains are the target, or b) users changing their email providers. Neither seems acceptable. This is presumably being seen on other lists besides the Evolution one, so perhaps list admins should be notified.
