This question is in the wrong forum.  I am assuming you are not running an SMTP server...

   The problem is problem in your mail client setup.  More than likely you need to turn on SMTP authentication.

You are running a virtual server as verizon.net?  You need to use there SMTP server if you are going to send it from thier domain smtp server.  There are swf / txt records that do not authorize any server to be any domain to prevent email spoofing.  You can only send emails from your domain or one w/out a TXT record in the DNS. Do you own the domain?
