I am using Outlook Express with my Netscape ISP mail account. I used to be
able to receive and send mail with Outlook Express, but now I can only
received mail. I have tried sending mail on several computers and I get the
same result:

The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was '. Subject
'test5', Account: 'pop3.isp.netscape.com (1)', Server:
'smtp.isp.netscape.com', Protocol: SMTP, Server Response: '550 Recipient
Rejected: Relay not allowed', Port: 25, Secure(SSL): No, Server Error: 550,
Error Number: 0x800CCC79

Netscape says it is an Outlook Express problem, but I have my doubts. Is
anyone else having trouble sending mail in Outlook Express with a Netscape
mail server?

Thanks
