I find it rather funny that the above page has this statement in it:

"Reject the request when the hostname in the client HELO (EHLO) command is not
in fully-qualified domain form, as required by the RFC."

Which is funny, because RFC 1123 section 5.2.5 also explicitly prohibits
refusing mail based on HELO failing checks.

"However, the receiver MUST NOT refuse to accept a message, even if the sender's
HELO command fails verification."

I guess postfix figures "an eye for an eye" is reasonable when it comes to RFC
violations...
