Hi all,
I am getting the following bounce back while sending to mail to one of my client.

Connected to (IP *****) but sender was rejected.
Remote host said: 550 5.7.1 H:DAD Connection refused due to abuse

Waht could be the issue and how to resolve it. ?

Your client's server is blocking your IP#. You should ask their postmaster.
