Running XP Home. Can send mail from WebMail so ISP says not their problem.
MS says "call Dell." Dell says "all is functioning fine, must be ISP
problem." Circle begins again.

Have reset account information, removed and reloaded OE6, deleted
'outbox.dbx'. Recently configured OE6 on new computer with same e-mail
account data and had same problem. I have disabled e-mail scan in my AV
program. Looking for more ideas.

Interesting. I just learned that I can post to newsgroup. (same
computer/ISP that I am having problem on)

Your posts to this newsgroup aren't being sent via the SMTP server in
question, Lu.

See http://www.insideoe.com/problems/errors.htm#relay550

If you're sending from a account, you must use the
comcast.net SMTP server, not that of another ISP (e.g., maine-rr.com;
verizon.net).

Norman,

Yes. Comcast has taken over Suscom. I am a Comcast customer with a
Suscom-Maine account. I call Comcast for customer support and they tell me
that my server is still pop and smtp.suscom-maine.net.

Your NNTP posting IP address tells me that you are a Suscom cable
customer.
DSL Reports tells me that Suscom has been taken over by Comcast. So which
customer is now providing customer support?

For Comcast customers, the mail servers a

Incoming (POP3): mail.comcast.net
Outgoing (SMTP): smtp.comcast.net

But I strongly suggest trying to find out who is now providing customer
support, and then finding out from support which servers you should be
using.

It is not a Microsoft problem, nor a Dell problem. Between Suscom and
Comcast, _somebody_ is dropping the ball about keeping affected customers
informed of the changes.

You need to beat on either Suscom, or Comcast.

Newsgroup posing uses NNTP (Network News Transfer Protocol) over port 119.
Outbound email uses SMTP (Simple Mail Transfer Protocol) over port 25. You
are posting directly to the Microsoft news server (msnews.microsoft.com),
not your ISP's news server. You will not have any problems doing that. The
trick is, can you post NNTP through your provider's NNTP servers? Comcast
outsources news to Giganews. I don't know what Suscom did for NNTP
service.

I can choose between msnews.microsoft.com and news.sf.sbcglobal.net. Most
of
the time I just use the MSFT news servers; but this time I will use the
at&t
Yahoo! HSI news servers.

Norman,

Comcast has stated that they have not yet started any server or email domain
name changes yet. Ran DNS report and am now wondering if my SOA record
might be messed up. NSLOOKUP identifies my old ISP domain as nameserver.
Sound like a path worth following?

That plus the fact that a "550" error is typically caused by an
unauthorized
relay attempt, I would say that something is FUBAR with the ISP. They
probably need to add the Comcast range of IP addresses that Suscom
customers
are getting to their ACL (Access Control List). Or change their servers to
require authentication, and _inform_ their customers of the fact that they
are changing to authenticated access, and provide the authentication
information.
