Dear Checkmk Community,
yesterday evening we migrated the mailing lists for Checkmk announcements, werks-* and appliance from https://lists.mathias-kettner.de to https://lists.checkmk.com and from mailman2 to mailman3.
So it’s time to say goodbye to the last host living under the mathias-kettner.de domain.
You might need to adjust your mail rules, as the domain changed.
Everything else should be as before.
