You misconfigure your MX, they send mail where the MX tells them to, you
blacklist them. That sounds innocent to me. You're killing the mail of
the third party, because of your mistake. Not only that, but you're failing
to let them mail your postmaster, because of your mistake.

One attempt tells you nothing. It's statistically useless. But you're
obviously stubborn enough not to see the point. Good luck running a mail
system that cooperates. I look forward to blacklisting you.
