Bug Description

Mailman rewrites nntp message ids when receiving messages from newsgroups, this results in broken threading since the messages loose the relation to each other.

I made a simple patch to make this behaviour configurable. When message id mangling is disabled, Mailman will add a new "X-Mailman-NNTP-Trace" header to keep track of looped messages bouncing between different mail2news gateways.

The attached patch was made against Mailman v2.1.9 and works for use since 04/2009.
Any change to have this included in the official release?
