question about headers
Posted: Sat Mar 31, 2007 3:31 pm
Not Swift-related, precisely, but hopefully someone here can clue me in. I'm struggling with "the Hotmail problem" (they silently black hole my newsletter all of a sudden). I've implemented (correctly, i hope) SPF, and am checking a few other things to ensure that the email looks legit. Looking at the headers, i noticed something a bit odd. The server i'm using has a hostname domain1.org, but the mail is coming from another domain, domain2.org. So, first, i passed domain2.org to the constructor, so that the EHLO will use that one. So far, so good.
But one of the headers is:
I thought that the 127.0.0.1 might be seen as a red flag (is it?) so i changed the the connection from 'localhost' to the IP of the sever. Testing this, i now see:
Does anyone know what the "unknown" is in reference to? And is it a bad idea to do this? I'm not too sure about the intricacies of fsockopen().
But one of the headers is:
Code: Select all
Received: from domain2.org (domain1.org [127.0.0.1]) ...Code: Select all
Received: from domain1.org (unknown [M.Y.I.P]) by domain2.org ...
