 DO NOT MAKE YOUR OWN DNSSEC KEYS. THIS WILL NOT SYNC CORRECTLY. This is due to issues with nsec3_narrow combined with AFXR.

 This script will automatically email the DNSSEC records to dnsmaster @ snt, which forwards to some syscommers and board. You can forward this mail nicely to servicedesk, where it usually ends up at Frederik.

+-The mail server could not deliver mail to snt@association.nl. The account

+This sometimes happens after upgrades?
+In any case, this happens because /etc/localdomains and /etc/remotedomains are wrong.
+cPanel has a tab "email routing" that is used to determine if cpanel is the email host for a given domain. Most domains have this set to automatic.
+It has happened multiple times before that cpanel thinks that it is not the host for many domains (presumably DNS does not sync fast enough, or caused by the hidden master DNS setup that SNT has).
+In this case. There is a script you can run to re-detect this: https://help.bigscoots.com/en/articles/1783776-whm-how-to-rebuild-etc-localdomains-and-etc-remotedomains-on-cpanel
