[ale] godaddy for DNS

[John Heim]

Well, the IP of the vm is 66.170.20.226 If you lookup www.iavit.org you get 
that IP. But if you lookup 66.170.20.226, you don't get www.iavit.org or 
anything like that. And there is no way I can fix that.

I don't think most mail admins filter messages where you can't do a reverse 
lookup . Half the legitmate mail on the internet would be marked as spam. I 
know lots and lots of people who make their gmail account look like their 
work account. I don't know how they do that but if you look at the message 
headers, they say the mail is from example.com when its really from gmail.

iavit.org used to be on dreamhost. We had
mailman lists configured to use lists.iavit.org. But if you did a lookup on 
the IP address for lists.iavit.org, you didn't get back lists.iavit.org.  So 
that part, at least, is no different than it used to be.

You need an MX record pointing the VM for mail to get delivered to
your server. Also you will want bith forward and reverse DNS matching
for your outbound email to really work. Most mail admins, block mail
from IPs that dont match.
