When you attempt to send
email through mail.yourdomainname, your email program is
using what's called "port 25". EarthLink and
MindSpring have blocked this "port 25", making it
impossible to connect to mail.yourdomainname and send email.
The solution in this case, would be to send email through mail.earthlink.net
or vipmail.earthlink.net. Should you have any
questions about EarthLink and MindSpring policies, please
don't hesitate to get in touch with their technical support
department.
