Hi I really like then new ISPConfig DKIM creation. I wonder what do I need to copy for creating backup? Do I need to copy only the keys in /var/lib/amavis/dkim or are there any other files? With opendkim there were 3 extra files where some config was saved.
You can dump the database and restore the keys and dns-records with a resync. If you want to save the keys, backup /var/lib/amavis/dkim and /etc/amavis/conf.d/60-dkim (this file contains the keys used with amavis).
