Hi,

...

Exactly what messages are you referring to? I don't understand test mails testing for bounces.

I mean the messages created by

[mta] verp_probes: yes

I thought that might be what you meant, but you said

To our confusion, test mails testing for bounces are sent from example.com

From: Mailman mailman@example.com To: Mailman Bounces mailman-bounces@example.com

Verp probes are always addressed to the bouncing user, never to mailman-bounces@example.com unless mailman-bounces@example.com is a list member with bouncing deliveries. They are also from listname-bounces+<token>@example.com, not mailman@example.com.

I don't know what messages you are looking at, but they don't seem to be verp probes.

Thanks for your reply. It seems the probes were triggered by some rejected example.com mails and I have no idea where the example.com mails are coming from.

I think what you are seeing must be some kind of spam. If not if you could post the complete raw message of one of these probes or probe bounces, I'll look further.

Some users also reported they got some "unsubscribed due to bounces" messages but the bounce.log contained only entries for them 7 days ago.

And were they unsubscribed? In general, unsubscription does not occur until some time after bounces are recorded. At some point, bounce score reaches threshold and a probe is sent. The probe may not bounce for days if the bounce is some downstream timeout. When the probe bounce is received, the user's delivery is disabled by bounce. This starts a process where the user is sent a warning at intervals until a limit is reached and the user is finally removed. The default settings are:

bounce_you_are_disabled_warnings = 3 bounce_you_are_disabled_warnings_interval = timedelta(days=7)

which means the user is sent 3 warnings, one immediately, one after 7 days and one after 14 days until finally being unsubscribed after 21 days.

An entry 7 days ago could be a bounce of a warning message.
