I am an EarthLink or a MindSpring customer and am unable to send
When you attempt to send email through mail.addr.com, 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.addr.com and send email.
The solution in this case, would be to send email through mail.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.
for another possible cause of the problem (if you
are not an EarthLink or a MindSpring customer).
