Planned Maintenance Advisory - Ubuntu Mailing List

[Jared Norris]

Good afternoon,

Over the last week or so we've been having some issues with the mailing
list, specifically with regards to DMARC authentication with some large,
free mail providers. This issue has affected a large proportion of the
mailing list subscribers.

We contacted the Canoncial engineers and they have been very responsive in
helping us to resolve the issue. The fix for this is non-trivial as it
involves upgrading the server to allow for newer versions of mailman to
cope with the upgraded DMARC requirements.

Affected users are unlikely to see this message as they will have been
automatically unsubscribed by the software. I am sending to the list to
ensure it's made available on the public archives [1] as affected users may
be following there.

To resolve this issue we have been advised of the following maintenance
advisory from Canonical engineers, please take note and contact the ubuntu
user mailing list moderation team [2] if you have any further questions or
concerns. The maintenance advisory details are as follows:


*Planned Maintenance Advisory (Service Affecting): Ubuntu mailing lists -
2017-09-04 00:00 UTC*





*In order to expand capacity and to provide better mailing list
deliverability to email providers using DMARC [3], we will be performing
service-affecting maintenance on the  Ubuntu mailing lists server, starting
from 00:00 UTC next Monday, 2017-09-04.  We anticipate this maintenance to
take no longer than 6 hours.During the downtime, there will be no emails
delivered on Ubuntu mailing lists.  All other Canonical-managed Ubuntu
services should remain up and be unaffected.Progress of the work will be
communicated in #canonical-sysadmins on Freenode IRC.  If you have any
questions or concerns please contact the Vanguard mentioned in the
#canonical-sysadmins channel topic and quote ticket uRT#30108.*
