You’re at the wrong place knocking on the wrong door.
And I really don’t see the use in replying to spam messages. Are you trying to tell the spammer to stop spamming you? At best, you’re just wasting your time. Worse, you could inadvertently click some link and get malware on your computer… or, if you let down your guard, you could end up getting scammed.
Dealing with spam (or rather not having to deal with spam at all) is the primary reason I stopped running my own server: Gmail (from Google Workspace) catches 99% of spam by default and the advanced filters take care of the rest.
