Hello again Roger,
The problem could be in two places, but strongly points to an
authentication problem with the SMTP server. Some providers have
switched how they operate so that in order to use their SMTP server,
they must first know that you are a bonafide user of their service.
They way they know this is by you "popping" your incoming email before
you attempt to send email. Outlook Express will most often attempt to
send email BEFORE it pops you incoming email and your provider will
"assume" you are trying to use their SMTP server as an unauthorized
user. This is one way they attempt to minimize SPAM going through
their servers.
123m.com has an article on this which is typical of providers that
have implemented user authentication:
http://www.123m.com/smtp.asp
"SMTP Authentication changes
Tech Document - T123m01101
Effective Thursday, December 20, 2001 at 12:01AM CST, 123m.com
activated User Authentication on our SMTP server(s).
What this means, is that you will need to have your POP3 client
software configured to log into the SMTP Server prior to sending mail.
(Just as you log in to retrieve your mail now, you will now be
required to login to send mail.)
This is easily accomplished by going into your account set-up in your
POP3 client (Outlook, Outlook Express, Eudora, PocoMail, etc.) and
checking "My Server Requires Authentication" under the Outgoing Mail
Server information. If an option exists, make sure you check "Use the
same settings as my incoming mail server"
If you did not make the changes after December 20, 2001 at 12:01AM
CST, you will not be able to send mail. You will receive an SMTP
Server Error 550.
Sample Error 550 Message:
The message could not be sent because one of the recipients was
rejected by the server. The rejected e-mail address was
'sample@123m.com'. Subject 'Test', Account: 'sample@123m.com', Server:
'smtp.123m.com', Protocol: SMTP, Server Response: '550 Relaying is
prohibited', Port: 25, Secure(SSL): No, Server Error: 550, Error
Number: 0x800CCC79
If you are currently using another ISP's SMTP Server, no changes are
necessary.
Your incoming mail will not be affected..."
This is most likely the problem, Roger.
However, the other possibility, if I read your question correctly, is
that only some of the addresses you are trying to send to exhibit this
problem and only when you use the SMTP server from your ADSL account.
The same addresses work properly when you send from your new account.
If I am accurate with this description, then it is very possible that
the server you are trying to send mail to has blocked your ADSL server
as what they believe to be a known relayer of SPAM and have "black
listed" any incoming email from your provider.
The best way to verify this would be to email the provider that may be
bouncing your email to ask if your provider is being blocked. Again,
if I understand your question accurately, bigpond.net.au is the
address that is bouncing your email and your provider that is giving
you trouble is runbox.com. If that is correct, email bigpond at this
page and ask if runbox is being blacklisted as a SPAM relayer:
http://www.telstra.com.au/contact/email.cfm
Do let me know if this answers your question and solves your problem.
If it persists, please do let me know Roger and I will be happy to
continue to find your answer. I do think that the first solution for
authentication should work for you. If not, please do clarify as to
whether it is just one or two recipients that give you the error or
all from the SMTP server on your ADSL account.
Search Strategy:
550, Error Number: 0x800CCC79

Hello Roger,
I've had my coffee and ready to go.
Let me summarize my understanding now:
We have runbox working and when you send email from your runbox
account when logged into runbox as an ISP and using their SMTP server
information, things now work. However, if you use your bigpond email
accounts and their SMTP server, you receive error 551. Is this
correct? If so, the problem is that bigpond does not see you logged
into bigpond and sees you trying to use their SMTP server as an
unverified user.
Earthlink explains it this way:
"The computer attempting to send email can not be verified as
connected directly to Earthlink. For example, the computer sending
mail is behind a firewall or has authenticated into another ISP. The
relaying denied is a conscious effort to stop spammers from using our
mail servers."
http://support.earthlink.net/mu/1/psc/img/walkthroughs/macintosh/email/eudora_lt_3.1.x/1097.Eudora.551relayError.psc.html
So, if this is correct, all you need to do is to use the runbox SMTP
server information on your bigpond email accounts in Outlook Express.
Keep the incoming mail server the same for this account (Outlook
Express / Tools / Accounts / email / xxx bigpond account) but simply
change so that you are using the runbox SMTP server as that is the ISP
you are currently logged into and have clear access to use. Your
return email address will still be a bigpond address and everything
should work as you desire. Be sure to check that the SMPTP server has
"my server requires authentication" checked and set as you have now
done for runbox email accounts.
Please do try this and correct me if I am misunderstanding the problem
at all. I think this should be the final piece of your puzzle.
Kind regards,
