New to ProMox..... 15 years on Barracuda and I can't make out the the logic or any method to simple block or quarantine based on words in the email header. Love ProxMox so far and I had good luck with header match words using BC so hope to continue with that with PM. Appreciate any detailed guidance!

you can also use the Mail Filter/Rule System to match headers with regular expression - that's what the "What Object" "Match Field" does.

might be a bit more user-friendly/flexible.
I hope this helps!
