I am using Outlook Express with my Netscape ISP mail account. I used to be

received mail. I have tried sending mail on several computers and I get the

The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was '. Subject

Rejected: Relay not allowed', Port: 25, Secure(SSL): No, Server Error: 550,

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

What you are seeing is a relay error; the sort I would get if I tried to
use that server.

I have a suggestion; why not set MS Outlook Express to use port 587? I just
tried to Telnet to 'smtp.isp.netscape.com', and I got the following:

| 220 dm17.mta.everyone.net ESMTP EON-AUTHRELAY2
| help
| 500 unrecognized command
| quit
| 221 Bye

I suspect that they do use authentication, though; even though "help" was
no help. As long as you don't get an error over STARTTLS, it should work.
MS Outlook Express, through version 6.0, doesn't support STARTTLS on ports
other than 25, though.

Tools Accounts Properties. On the "Servers" tab, be sure to check "My
server requires authentication"; but _DO NOT_ check "Log on using Secure
Password Authentication", that is a Microsoft thingy, little used outside
of an Exchange environment. On the "Advanced" tab, change the "Outgoing
mail (SMTP)" port to 587.

As I said, as long as they don't require STARTTLS with the log in, this
will work. From any ISP connection.
