Dear users,
hoping someone can point me in the right direction.
Since we set up mailman3 on Ubuntu last year we have migrated to new DNS servers.
The Ubuntu host's systemd-resolved service is correctly using the new DNS servers for lookups and postfix is honouring the change as well.
However when messages are sent to mailman3 lists we're still seeing hits on the old DNS servers.
I have tried to find a config that references the old servers but have not been able to find one.
Can anyone provide a tip on where to look next or if there is something that mailman3 requires to recognise the change?
Thanks, Simon.
