HELO or EHLO are easily faked, and IMHO it wouldn't be safe to do any
(permanent) filtering on that.
Basically, the program/person sending the mail can decide what to put
in the HELO-line. The receiving mailer can then check from which IP
adress that particular connection is from, and can act on that
information (log something, deny service, etc.).
