@ryanprior I've run my own mailserver continuously for over half of my life, so yes. 🙃
Personally, I'm hard in the "don't pay the protection racket" camp. The expensive delivery services *are providing service to spammers*, and using the money they rake in to keep themselves off slimy pay-to-get-removed lists.
I'd rather pay libel lawyers to go after the lists if it came to that.
