Fail2ban & dovecot error messages in syslog?

I’m seeing these errors frequently in the system log. Both of these services are disabled in VirtualMin. Is there a way through VM to sort this out?

This is a systemd issue, check out the configuration files in /lib/systemd/system and look at the [service] section. You’ll find a line PIDFile= simply remove the /var from the front of the path since /run is now mounted as tmpfs on modern linux. Legacy linux used /var/run and maybe some obscure flavours. If you get stuck check out the documentation on SystemD services configuration for some background.
