Putting up a chaeck for Verifiable HELO/EHLO Check gives a warning message on Yahoo ... The Header is as follows:

Received: from web13007.mail.yahoo.com ([216.136.174.17]) by
dome.domain.com with smtp (Exim 4.42)

Checking the same for mail from some.domain.com to Yahoo has following headers as visible at Yahoo:

from XX.XX.XXX.XXX (EHLO some.domain.com) (XX.XX.XXX.XXX) by mta138.mail.scd.yahoo.com with SMTP; Thu, 16 Sep 2004 21:04:31

Are Yahoo's Header's Technically Correct wrt verifiable EHLO/HELO?
