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.
