SMTP error 550

[Charlie Bress]

This post is going on two newsgroups. One for XP and one for OE as I cannot
determine where the problem really lies.

The background:

The system is a new (actually refurbished) unit with XP Pro and SP2
installed. It also has automatic updates installed. The user is using IE and
OE as installed. The user is the sole account and so is the administrator.
The ISP is a cable.provider

The problem:

Email can be received but not sent. The error that comes back says "SMTP 550
relay not permitted, Secure SSL No, Server error 550 Ox800ccc79." The quote
may not be exact, but has the pertinent information. The internet mail
options were set up with guidance from the ISP. I further checked by phone
as we went step by step through the setup. The ISP contends it is a MS
problem. The user and I are on the same ISP.

What has been done:

I have looked through the Knowledge Base and have tried some of the simpler
tasks. The XP firewall is not enabled and Zone Alarm is not yet installed.
The "server requires authentication box has been checked and unchecked.
Temporary files have been deleted. I have printed out the article regarding
"SMTP behavior in.WindowsXP.." I have not yet attempted to go through the
procedures it lists for testing the relay. At this point it must be obvious
that I am not versed in the workings of SMTP.

With hat in hand, so to speak, I am looking for advice on getting his
problem behind us.



Thanks

Charlie

I shall assume your ISP is also providing the SMTP server? The error would
seem to point to either using an SMTP that your IP is not allowed to use
(Earthlink SMTP requires your on a Earthlink IP) or you have not setup
Outgoing Mail Server Requires Authentication correctly.
