That's actually not how I meant what I said.

My question didn't really mean block it for yourself, I was trying to
say "How would some individual 'cause' a particular domainname to get
onto some publicly available and widely used blocklist which is made of
domainnames?"

The inane original 'question' [if you can call the absurd notion a
question] was about the OP wanting their domainname to somehow be
blocked by great numbers of recipient servers so that those recipient
servers couldn't possibly accept the items and then generate a newmail
delivery status notification to the bogus From.

So, the notion would 'require' that somehow 'magically' there would be a
blocklist widely used by servers which blocklist was made of
domainnames, and thus all of these servers using this imaginary
blocklist wouldn't be bothering the OP with their backscatter.

I can't believe we are discussing the original post.
