Category: bounce detection Group: 2.1 (stable) Status: Open Resolution: None Priority: 5 Submitted By: Matthias Andree (m-a) Assigned to: Nobody/Anonymous (nobody) Summary: 2.1.7 (VERP) mistakes delay notice for bounce

Initial Comment: Greetings,

I just got the bounce action notice specified below.

I am running Mailman 2.1.7 with SF Patch #1405790 on Python 2.3.4, SUSE Linux 9.2 i586, Postfix 2.2.9.

It appears as though Mailman 2.1.7 were not properly detecting this apparently RFC-1894 compliant notice as a "delayed" notice which is definitely a "soft bounce", if it is supposed to contribute to the bounce score at all. I looked at Mailman 2.1.4 or so which appeared to make efforts to not count "delayed"/deferral notices at all, but that didn't work at the time for Postfix deferral notices and was IIRC fixed later.

My setup is VERP enabled, uses VERP for almost everything and uses monthly reminders for this list.

I masked the list host by ... and the subscriber's domain by example.com and the last two components of the IPv4 address by X, without loss of accuracy I hope, to protect the site from spammers.

Can anyone shed any light why Mailman 2.1.7 with said patch considers the delay notice a "hard" bounce?

I don't have time to do debugging right now (end of the month might work), but applying a patch will probably work.

I pasted from Emacs/Gnus, and this is the mime structure as seen by Gnus, it looks intact.
