UN_educated guess - I don't use DKIM... does it stop happening when you
restart your DNS recursor instead of rebooting?

Hello again.
I have a problem that arises after my mail server has been up for maybe
two days. Suddenly all DKIM-verifications in SpamAssassin says
DKIM_INVALID while those look valid to be when looking to mail source
code. It works again correctly after I reboot the machine. This starter
as it is when I upgraded from Debian Stretch to Buster, I think.
