Thanks a lot for reading the relevant part of the announcement to me
again, however reading isn't my problem - I do not understand what is
written :|

When you say, the check_helo_mx_access restriction applies to the MX
host of the host given in the HELO command, what does this mean? I
understood this to mean, that the check applies to the hostname given in
HELO. Is this wrong?

Also, I understood this to mean that it restricts the acceptable values
when "HELO <hostname>" is sent? Wrong again?

If not, why is the hostname "this-is-verisign.com" acceptable in the
HELO (or MAIL FROM) command?

And if I understood this wrong - what would be values for HELO or MAIL
FROM which should cause the 451; or when should this code be returned?
