Problems sending mails from blueyonder smtp to blueyonder email addresses

Hi,
I have a program running on a blueyonder broadband connection. This
program sends out daily email reports via smtp.blueyonder.co.uk. The
reports are sent to a list of addresses. They are sending fine to any
address that is not on the blueyonder domain. But if the address is
(E-Mail Removed), it is rejected. I get back the following
message from blueyonder smtp;

This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
(E-Mail Removed).

There is a dat file attached with the following:
Reporting-MTA: dns;cluster5
Received-From-MTA: dns;smtp-in3.blueyonder.co.uk
Arrival-Date: Wed, 17 Nov 2004 18:17:57 +0000

Final-Recipient: rfc822;(E-Mail Removed)
Action: failed
Status: 5.0.0
X-Display-Name: (E-Mail Removed)

The blueyonder addresses I am sending the reports to are definately
valid because I have been mailing these people daily through outlook.

I have been in touch with blueyonder technical support and they
couldnt tell me anymore than "Hmmmmm....Yes, it should be working
alright". Very Helpful!

If anyone could shed some light on this or if somebody has had similar
problems, it would be much appreciated if you have any suggestions. As
I said, the problem is purely with blueyonder email addresses. All
other addresses are receiving emails fine!

Cheers,
Niall

This may be the problem - I send out a mass mailing every few months and
obviously get about 2% mail delivery problems because people have changed
email addresses, joined the list using the wrong email address etc.

As a result the IP I use gets treated as a SPAM sender and Yahoo! very
kindly blocks the IP address because I send to too many invalid addresses.
Is it possible that this is happening with you? A mate claims that Yahoo!
run some UK ISPs for BT.

Can you try using another email client to send them (just to make sure it
isn't your current one mangling them in some way). Do you have an
outgoing-email virus scanner (such as Norton), and if so can you disable it?

I dont think this is actually the problem. The email addresses I am
sending the reports to are actually valid addresses. Its not exactly a
mass mail either as the reports are only going out to 6 or 7 different
addresses. The only ones that are being rejected are blueyonder email
addresses!

Include your own addess in the list and see if this provides
something meaninfull ?

Or:
Send a (dummy) message to the same address from another mail
program. This also could provide some meaningful answer.

What you should get is an SMTP error number. Something like 554
(service unavailable), 504 (rejecting message based on content)
etc.
