I think the big thing is that reverse look up returns a valid name and not just a "not found". The ISP controls the reverse lookup on the IP address.<br><br><div class="gmail_quote">On Thu, Dec 29, 2011 at 9:06 PM, John Heim <span dir="ltr"><<a href="mailto:john@johnheim.net">john@johnheim.net</a>></span> wrote:<br>

anything like that. And there is no way I can fix that.<br>

I don't think most mail admins filter messages where you can't do a reverse<br>
lookup . Half the legitmate mail on the internet would be marked as spam. I<br>
know lots and lots of people who make their gmail account look like their<br>
work account. I don't know how they do that but if you look at the message<br>
headers, they say the mail is from <a href="http://example.com" target="_blank">example.com</a> when its really from gmail.<br>
<br>
<a href="http://iavit.org" target="_blank">iavit.org</a> used to be on dreamhost. We had<br>
mailman lists configured to use <a href="http://lists.iavit.org" target="_blank">lists.iavit.org</a>. But if you did a lookup on<br>
the IP address for <a href="http://lists.iavit.org" target="_blank">lists.iavit.org</a>, you didn't get back <a href="http://lists.iavit.org" target="_blank">lists.iavit.org</a>. So<br>
that part, at least, is no different than it used to be.<br>
