I don't think there's point in blacklisting hoat that sends fake helo, when
you can block the helo itself.
yes, I think that such helo should be blocked and I block it wherever I can.

Correction: it is not the mid, it is the helo.
oh... this is something quite different.
But unless multiple servers start implementing reject_unknown_helo_hostname,
such companies ignore to change that...
... apparently with possibly reject_non_fqdn_elo_hostname and
reject_invalid_helo_hostname. and smtpd_helo_required=yes of course

Two well known companies in my country persist in making the mistake of writing
their mid with a non-public fqdn, violating the rfc. It has been so for the
past three years, with me sending detailed, manually written error messages to
their painstakingly collected admin addresses. Their answer is that everybody
else accepts their invalid mid, and their servers are enterprise ibm /
microsoft shitware that they are unwilling to fix. Since we get a lot of their
emails, I decided to scale up their problem. There are many blacklists, and I
have no intention to go through each idiosyncratic procedure.
Is there an ombusdman that superintends the major blacklists and enforces rfc
compliance through them?
