Some of your rules in the Mail Filter - Who Object - Regular Expression are invalid.

Check

I would recommend you help yourself with a regex generator.
This one is good (example when I was trying to whitelist something)

Thanks for the reply, we do use the tester built in to proxmox and it passes.

.+@badguys\.com is another method we use.
What pattern are you utilizing to black/whitelist a domain?
