Looks like there might be a little more to do, with regard to email
reputation.
SPF and DKIM signing fail, and there is a published DMARC record that
quarantines 100% of DMARC failures. So the list emails are going to end
up in spam folders (they ended up in my Gmail spam folder) because
SPF/DKIM/DMARC all failed.
2a0a:bb00:0:44::1d needs added to the
mailman.ampr.org SPF record
and it appears the
mailman.ampr.org emails are being signed with an
ARDC.NET DKIM key rather than a
mailman.ampr.org DKIM key

Hello All,
FYI, we had an issue with the mailing list server last week:
The server the mailing list is hosted on experienced an unexpected reboot.
The server came back up ok and all the services associated with the mailing
list continued to run, so Nagios (the application we use to monitor our
systems) did not report any issues. However, the sudden reboot had
corrupted several open files associated with the mailing list software
(Mailman 2.1) and the 44net mailing list was not passing emails. As the
list often goes through quiet periods this was not noticed for several days.
Unfortunately the backup period for the server was only set to a few days
and by the time the issue was investigated all the available backups were
of the corrupted files.
As the longer term plan was always to migrate from the older (now
unsupported) Mailman 2.1 to the latest Mailman 3.1 the decision was taken
to migrate the mailing list to a new server. ARDC already has a Mailman 3
server for some internal mailing lists, so we migrated the 44net list there.
I am pleased to report that the archives from the old server were
successfully migrated over, so no loss of data there thankfully.
The web interface for the new home of 44net can be found here:
https://mailman.ardc.net/mailman3/postorius/lists/44net.mailman.ampr.org/
The MX record has been updated to point to the new server, so you should
continue to send emails to 44net(a)mailman.ampr.org to post to the list.
I want to take this opportunity to thank John - KI5D for hosting the
mailing list since we had the last big crash in 2012. The mailman server,
with John looking after it has provided excellent service to the community.
John is going to continue to help out by acting as admin for the 44net
mailing list on it’s new home.
Best 73,
Chris - G1FEF
