I am myself not quite fully understanding how this is connected and
routed between the debbugs BTS and mailman but that isn't the problem
you experienced.  Because your mail was not being delivered.  So it
didn't even get to that point yet.

I rather wish I had gotten to this sooner because it will be a long
gone message now.  But here it is saying that www125.your-server.de is
not able to deliver to debbugs.gnu.org.  But I see no reason for
debbugs not to be accepting this email.

It would make me think greylisting too.  Except there is no
greylisting on debbugs.

On debbugs.gnu.org it is using Exim for the MTA mail transport agent.
That's the first layer.  Mailman and the BTS receive messages from
exim after exim receives it from the outside world.

This question of what and why would be what is happening between
www125.your-server.de and exim on debbugs.gnu.org.  If it doesn't get
passed to exim then exim can't pass it to Mailman or the BTS.  After
exim gets the message then we would be able to track it through
mailman, human moderation, and the BTS.

I know I am too late to this party...  Sorry!
