[Mailman-Developers] qmail VERP patch changes

[Andrew A. Raines]

I'm not sure if Colin still reads this list, but I had to make a
couple of changes to the qmail VERP DELIVERY_MODULE on
Sourceforge[1].  Namely, the default QVERP_FORMAT didn't make
sense, but a docstring addition seemed warranted as well.  A
patch to Qmail.py is attached.

 the format of the VERP header before it's passed to qmail for interpolation.

 qmail-inject is unfortunatly more sensitive than Mailman about the format
 of messages passed to it, and will sometimes refuse to deliver one.  If
