Seems like it's a DNS problem with BT internet. Go on their automated tech line and it will give you alternate DNS settings for you TCP/IP connection.

Number 0800 169 0199

Several others have reported the same issue on other sites.

Thanks for your speedy reply.

I've checked with the ISP & added alternative DNS settings, web pages are OK.  Also the message indicates that the e-mails getting sent ok but keeps getting rejected.

HELP!!!!

I checked around a bit, and it seems there are a couple of solutions to your problem. The reason is that your addresses are not recognised by BT Internet's SMTP servers. This usually happens if the sender is in a domain which is registered with a different hosting company.

1. You can register your domain name with BT Internet by this link: http://www.btconnect.com/maildomain/

2. You can transfer the hosting of your domain to BT Internet

Hopefully one of these can help you out.

The problem turned out to be caused by having configured ETRN to retrieve emails from the ISP hosting the emails and having the SMTP connector relaying through the ISP providing our ADSL. When we removed the ETRN setting all was well.

Thanks for your assistance.
