The problem "may" be that if you want to use Earthlink to send the mail, off their system, (it would be easier to use the Google SMTP), you need to use SMTPAUTH.EARTHLINK.NET with port # 587 with your full Elink mail address and password.
Yes, they have several email carriers on the phone & an option to add one not listed, that's what I did. I can get to settings, but
it's for everything but the pathways/ports. OK, I think I just stumbled on how to do it, geeeze! LOL Thank you for your help.
What I have showing is POP Server pop.mindspring.com, server port 110, is that where I put in the changes?
