the message we receive is below
This is the mail system at host know-smtprelay-4-imp.
I am sorry to have to inform you that your message, "TEST AGAIN 3`", could not be delivered to xxxxxxxx.ntlworld.com.
The remote mail system said;

The original message is attached.
Welcome to the forums, I'm sorry to see you have been having trouble with emails being bounced as Spam.
There has been a change to our systems recently which should prevent this from happening.
If you are still having trouble please pop across the headers
of the failed sent email, which should be included as an attachment in the failed delivery notification/ bounce back message. Send it via PM (purple Envelope, top right hand corner).
Speak to you soon.
