Re: [Mailman-Users] Patch for use of Postfix VERP support

Hi Fil,

I've done the following, with little success so far:

1. applied your patch to Mailman/Defaults.py and Mailman/Handlers/SMTPDirect.py
2. added the 2 configuration lines in Mailman/mm_cfg.py
3. restarted mailman :-)
4. added to /etc/postfixmain.cf the line smtpd_authorized_verp_clients=127.0.0.0/8
5. reloaded postfix

But no luck: I still receive messages with Return-Path: <test-bounces@rezo.net>

What you've done so far is to ensure that when and if Mailman uses VERP, it does so by asking Postfix to create the VERP return path, instead of doing it by itself (which would require it to deliver the message to Postfix once for every recipient).

You also need to tell Mailman when to actually use VERP. My mm_cfg.py contains:

VERP_PROBES = Yes VERP_PASSWORD_REMINDERS = Yes VERP_PERSONALIZED_DELIVERIES = Yes VERP_DELIVERY_INTERVAL = 1 VERP_CONFIRMATIONS = Yes VERP_STYLE = 'Postfix'
