So you want to know what HELO your system is sending with?
I normally just email an account hosted on another MTA (e.g.
Hotmail), and check the headers for the sending host info:
Slightly forged and over a few lines to hopefully be a bit more
visible
| Received: from
| myhelo.mydomain.com (myptr.mydomain.com [1.2.3.4])
| by mc2-f3.hotmail.com with Microsoft SMTPSVC(5.0.2195.6824);
| Thu, 26 Aug 2004
And accessible via a web GUI, though some decoding required ;)
