Hello everyone, I've just completed migration of the DebOps mailing list server from the old Mailman 2.1.x version to Mailman 3.x installed on Debian Buster - all with DebOps of course. The migration was done by setting up a new VM, therefore IP address of the server has changed, which might impact e-mail delivery. The new service also uses DomainKeys to sign outgoing mail messages, which also can impact message filtering on the recipient hosts. This message is a final test to see if everything was set up successfully. If you want, you can check the new web interface and archives on https://lists.debops.org/. Let me know if there are any issues with the service. Now back to our regularly scheduled programming, Maciej
