Mails not reacing HOTMAIL.COM

[Esni]

Is there a way to see the HELO straight? atm. i can check the recievers header-inffo:

Authentication-Results: mta137.mail.re3.yahoo.com from=domain.com; domainkeys=neutral (no sig)
Received: from 123.123.123.123 (EHLO mail.domain.com) (123.123.123.123)

Message-ID: <3230.83.245.169.83.1193261111.squirrel@domain.com>

This is the yahoo-header inffo:
123.123.123.123= our ip
domain.com = our domain

EHLO seems to be correct?
