Just to continue a bit, -in case you’re also running opendkim- these were the config changes that were updated and the selections I made:
spamassassin:
local.cf -> N
iptables before.rules -> N
50unattetended-upgrades -> Y
logind.conf -> N
sysctl.conf -> Y
apache2.conf -> N
default-ssl.conf -> N
samba -> Y
moduli -> Y
sshd_config -> N
jail.conf -> Y
security2.conf -> Y
/default/opendkim -> Y (!)
opendkim.conf -> Y (!)
apache.conf -> Y (!)
The (!) means changes were needed. Opendkim is now running chrooted so change to the sockets were made. The one thing that was a bit of a headache is that you need to re-compile the systemd init script by running “/lib/opendkim/opendkim.service.generate”, otherwise all change related to the socket settings in /etc/default/opendkim and /etc/opendkim.conf were ignored.
