[Mailman-Users] AOL now bouncing ALL email from ALL mailman systems

[Links at Momsview.com]

Serious issue for those with aol subscribers.
I'm currently whitelisted with aol and usually have no problem with mail delivery.
Currently running 2.1.3


This morning I noticed aol bouncing just about all of the emails from my mailman server with one or the other of the following
bounce messages:

Oct 23 09:39:34 myserver postfix/smtp[5615]: 974515884F8: to=<user2 at aol.com>, relay=mailin-04.mx.aol.com[64.12.138.152], delay=1, status=bounced (host mailin-04.mx.aol.com[64.12.138.152] said: 500 SYNTAX ERROR, COMMAND UNRECOGNIZED)
Oct 23 09:39:34 myserver postfix/smtp[6435]: 1ED73588177: to=<user1 at aol.com>, relay=mailin-01.mx.aol.com[64.12.137.89], delay=0, status=bounced (host mailin-01.mx.aol.com[64.12.137.89] said: 554 TRANSACTION FAILED)

I spoke with the aol postmaster support line and they confirmed that the problem is due to the form of the mailman reply-to address to process bounces:

listname-bounces+username=aol.com at momsview.net

They don't like the "=" in the address.

Again this appears to be due to a recent change in aol's mail server software.

I'll update once I hear back from aol
