problems sending email this morning - any ideas?

The e-mail system was unable to deliver the message, but did not
report a specific reason.  Check the address and try again.  If it still
fails, contact your system administrator.
    < c2beaomr06.btconnect.com #5.0.0 SMTP; 550 SC-001 (COL0-MC1-F48)
Unfortunately, messages from 213.123.26.184 weren't sent. Please contact
your Internet service provider since part of their network is on our
block list.

Error message above was received this monring - I have tried to send several emails to several different addresses - they all come back with the same message.  BT is our ISP and our email is through BT too so why are my emails being blocked?

everything has been working fine up until now and we haven't changed anything so I am assuming this is a BT problem?

nslookup 2beaomr06.btconnect.com
Server: vnsc-bak.sys.gtei.net
Address: 4.2.2.2

*** vnsc-bak.sys.gtei.net can't find 2beaomr06.btconnect.com: Non-existent domai

An open DNS 4.2.2.2 what able to recognize the MX record. There's your problem. Good luck.
