Describe what you would like us to do:

Some months ago I had a lot of bounces alerts :

~~~~
To: server-owner@lists.fedoraproject.org

The attached message was received as a bounce, but either the bounce format
was not recognized, or no member addresses could be extracted from it. This
mailing list has been configured to send all unrecognized bounce messages to
the list administrator(s).

I removed the user miminar@gapps.redhat.com from the server subscription list after checking the address., and the bounces stopped .

Now they were back, multiple times, several days in a row (last week while I was on vacation). I checked our subscripted users list, it does not contain that address. Maybe you can check, what is going on. It is neither urgent nor likely to be harmful, but it is annoying.

When do you need this to be done by? (YYYY/MM/DD)

Not urgent.

Yeah, I am seeing this on a number of lists.

Interestingly, the bounces I see are all from January... like it's processing a backlog or reprocessing old bounces... Very odd.
We will need to investigate.

Other lists seeing lots of bounces:
devel
devel-announce
epel-package-announce

It's in feb now... I really don't see how/why this is happening yet though. ;(

I have had no time to investigate this much, but it seems to be that it's processing all the old bounces slowly...

It is also unsubscribing some people for bouncing. So far as I can see from a quick check, those unsubscriptions are valid, ie, there's a real bounce that caused it.

It's up to april 22nd now.

The entire backlog was processed. It also marked a bunch of people as 'suspended' then just today (a month later) it's unsubscribing people with bounces.

I think it's processing as expected now, but if you see some cases where it failed I can investigate those more?

ok, please do open a ticket if you see this anymore...
