Hello, Is recipient filtering an outgoing filter to block from sending to certain e-mail addresses or is it incoming filter ? what is the difference when compared to Sender Filtering ?

Hi, you can configure recipient filtering to block inbound messages for specific recipients in your organization. If an inbound message contains a recipient that is on the Recipient Block list, the Edge Transport server sends a "550 5.1.1 User unknown" Simple Mail Transfer Protocol (SMTP) session error to the sending system. For more and detailed help kindly read this article. Recipient Filtering I hope this will help you. Regards. Shafaquat Ali.
