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
that has someone else with a compromised pc or is a favourite for spoof FROM

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.

At least Bob's one sends out a bounce message, I would normally repeat the
reply on a browser based account. I just wondered what others make of this
practise of tarring all with the same defamatory bounce comment etc
It seems some such bogus "blacklist" filters do not send bounce messages
which compounds the felony, because you are left with the impression they
have received and com stopped at that point, and the recipient believes that
the sender has not replied.
