This means that we have blocked sending of a non-delivery report type message. This would be an email, typically from a customer server, that is a bounc eback message. Rather than rejecting the incoming message at SMTP time, the customer mail server has accepted the incoming message and then decided that it was now wanted, and generated a new email back to the original sender saying that the message has not been delivered.
We don't allow sending of bounces back messages due to backscatter problems. -
In these cases, please configure your email server to reject mail at SMTP time, or to send messages by MX records rather than relaying through smtp.aa.net.uk.
We catch this by matching a null sender address,
