Well, the mail adress got disabled, and the user got warning mails ("Your subscription for list mailing list has been disabled"). As none of the list owners did that, I don't think there is any other explanation. Please note that individualsation was enabled, so all mails are sent out with per-subscriber mail envelope address, which then makes bounce detection quite straight-forward.
If by 'individualsation was enabled' you mean messages were VERPed, there could be a bug here.
Yes, that's what happens.
There are a couple of considerations. First the vacation responder should not respond to list messages. See <https://www.rfc-editor.org/rfc/rfc5230.html#section-4.6>.
I fully agree with you, and already responded with the same remark to the user before sending my initial mail here.
That said, bounce processing should treat even a VERPed message as unrecognized if it doesn't look like some kind of DSN. This may not be the case in MM 3.
Thanks, that's what I also think. Looking at the returned mail, they definitly don't look like DSNs / bounces to me.
Anything I should be doing re this topic?
Thanks, Andi
