Re: SMTP error 550

Then it's most likely related to the authentication as outlined in this KB article:

XCON: NDR with Error 0x800CCC79 When You Send SMTP Mail from Outlook Express:
http://support.microsoft.com/default.aspx?scid=290808

And Comcast does require authentication under Tools/Accounts - Mail tab and double click the account involved, then open the Servers tab and at the bottom, look for the info about "my server requires authentication." That should fix it.

Jim we are on the same ISP, but I am posting from my system that has
always worked.
My friend does not use NG's so we haven't tried that yet. She doesn't seem
to have an AV program running. At least there is nothiing obvious. She didn't put one on and doesn't have Norton or McAfee listed anywhere.

550 errors are associated with relaying. Are you connected to the ISP you
are trying to send the mail through? See the info at this link for more:

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
