I have my own domain, so I called Earthlink, they told me to use smtpauth.hosting.earthlink.net, that did not work. I then tried my own domain with adelphia settings which are mail.adelphia.net, still did NOT work, then I tried smtp.sprintpcs.com, once again...you guessed it, still NOT working. Any suggestions would be helpful in setting up my Treo 700.

Thank you in advance,
