            Bug ID: 30586
           Summary: More data about Mailman bounce-based unsubscriptions
           Product: sourceware
           Version: unspecified
            Status: NEW

Thank you. I conveyed this data to the Red Hat It team under INC2656812.

I looked at my own logs, and one optimization you could make is to set the
outgoing EHLO argument to match what the PTR record says (it's currently
sourceware.org, while the PTR record says server2.sourceware.org). That
difference should not matter, though, because sourceware.org has the same IP
address.

I set:
smtp_helo_name = server2.sourceware.org
But not a fan, since if we switch servers (server3.sourceware.org is a hot
spare) we will have to manually update this setting.

The default ($myhostname) might be more appropriate, assuming that the system
host name is set to server2.sourceware.org and server3.sourceware.org.

I don't doubt that there are still many bounces. Mailman is still sending me
alerts about them.

But $myhostname is set to sourceware.org. And $myhostname is used in a lot of
other places. So I don't want to change that. Is there a way to get the system
host name if $myhostname is explicitly set? Then we can set smtp_helo_name to
that. It isn't fully clear to me that this setting matters. In what way is the
helo name used for determining whether or not to bounce the message on your
side?

I don't think there's any RFC-compliance or spam-hygiene related benefit from
choosing one vs. any other DNS-level alias of the server.

RFC 1123 section 5.2.5 comes to my mind (the “principal host domain” part), but
it says later on that a mismatch should not be treated as grounds for
rejection. It was just a stab in the dark about what caused the problem.

It would be great if you can somehow match them up with logs on your side with
an explanation why they were bounced.

It looks like no more "554 Email rejected due to security policies" bounces
have been seen for more than 2 days now. Could you confirm emails seem to be
flowing again to your address?

I just received:

“
Your membership in the mailing list Gcc-patches has been disabled due
to excessive bounces The last bounce received from you was dated
10-Jul-2023. 
”

Any idea what bounces may have triggered this, and how far back they go?
Perhaps it's an actual spam rejection this time, which triggered Mailman into
action combined with the old bounces still stored in the system?

We are seeing the "554 Email rejected due to security policies" bounces again
since this morning. It does look like they are all from rivia.ai and it looks
like they contained HTML (which we strip):

There doesn't seem to have been any more bounces from mimecast to your address
since those on July 10.  Are you still having issues with subscriptions or
missing/bouncing emails?
