MSFE no longer working after swap of IP addresses between two systems with MSFE licenses

I just spun up a new server to upgrade the OS to Almalinux 8. I purchased a new license to MailScanner FE and had ConfigServer install it on the new system. When the new and old systems swapped IP addresses, MSFE on both servers stopped working up in WHM (i.e. when I visit /cgi/configserver/mailscan...

CSF Blocking email from IP addresses not listed in allow

On one of my servers, on or about Feb 1, 2023, CSF started blocking email connections from any IP address that was not listed in /etc/csf/csf.allow.
