Markus Mohr wrote on Aug 15 about a mail loop undetected by Mailman while
the looping messages included :

>X-Autoreply-From: <his mailaddress>
>Precedence: bulk
>X-BeenThere: <mailinglist address>

Markus: "If I understood correctly each of this lines should have stopped
mailman from resending his answer to the list!? It didn't though and so
created a lot of unwanted mails. :( I couldn't find a trigger in the
configuration to change this behaviour."

We had two similar mail loops last week on two of our Mailman 2.0.4 lists,
both triggered by the same subscriber. The X-Autoreply-From header was
absent though, but the Precedence and X-BeenThere headers appeared as
reported by Markus.

Any insights, or a hint how to prevent more loops of this kind? Thanks!
