If you did not have a crap email "spam" blocker I could have successfully
replied to your email.
Instead a bouncing statement that defames people who happen to have an ISP

IMHO, blacklisting ISP SMTP servers is not good practice these days; the
bulk of spam originates from compromised PCs in botnets. The proper
defense is either an intelligently designed greylisting procedure that
doesn't discourage the sending MTA from retrying, or verifying with
a callback that the sending MTA is in fact a legitimate SMTP host
(with HELO) -- I doubt that most compromised PCs will answer correctly.
