Bug Description

This patch adds support for Postfix's XVERP ESMTP
extension for doing VERP on delivery instead of
requiring Mailman to inject the message once per
recipient when VERPing.

This patch is against Mailman 2.1.2

To make it work, add:

VERP_STYLE = 'Postfix'

to And to go back to Mailman's way of doing
VERP, you can set VERP_STYLE = 'Mailman'

I for one find this a valuable contribution. It doesn't apply perfectly cleanly on the latest release of mailman but it does apply pretty easily by hand. This patch makes a big difference on system performance.
