Mailman Upgrade: Wednesday 23th of November, 09:00 - 10:00 CET

[Andrea Veri <av gnome org>]

Hi,

tomorrow we'll be performing a minor version upgrade of our Mailman
instance, specifically from release 2.1.15 to release 2.1.23 [1]. The
following services won't be reachable (mails will be kept in the queue
and flushed as soon as the upgrade has happened) during the
maintenance:

1. mail.gnome.org

The upgrade has been specifically scheduled to resolve the mass
un-subscriptions a few list owners have been reporting since the time
Yahoo and AOL (and any other DMARC aware domain) have decided to
enforce DMARC policies. On this side there will be two user visible
changes:

1. the From address will be modified (From: Andrea Veri
<infrastructure-announce gnome org>)
2. the Reply-To header will be modified as well (Reply-To:
<infrastructure-announce gnome org>, <av gnome org>
3. the first and second point will be true only for the senders behind
a domain that has a DMARC policy published on the DNS (it being reject
or quarantine or none. Mailman makes a call against the DNS resolvers
and looks for a DMARC record for the target domain)

This particular option can be overridden on a per-list basis with the
following values [3]:

1. Reject
2. Discard

As usual please keep an eye at [2].

Have a great day,
