My ISP is Adelphia (actually now Time Warner) and I want to set up a laptop computer to be able to access the Adelphia POP3 emails that normally go through the Adelphia account and ISP connection on my desktop computer. When I set up Outlook Express on the laptop for this account and am connected through another ISP other than Adelphia, I can receive my emails fine but when I try to send and email I get the error message:
The message could not be sent because the server rejected the sender's e-mail address... Adelphia', Server" mail.adelphia.net", Protocol: SMTP, Server Response: '553 Authentication is required to send mail as <xxxxx@Adelphia.net>', Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCCC78
Is there a way to be able to send email from Outlook Express that is set up for this Adelphia account when I am connected to a non-Adelphia ISP connection?
Thanks for any suggestions.
