Set Message Filtering
The message filter list is a list of defined addresses or address spaces. You can use message filtering to add or modify domains or users who cannot deliver e-mail to your organization.
This list applies to all IP addresses configured on every Simple Mail Transfer Protocol (SMTP) virtual server in your organization. However, message filtering only occurs when you enable it for a particular IP address that is bound to a virtual server. You can have more than one IP address associated with an SMTP virtual server.
To create a message filter list
Important When entering names, you must use an SMTP address format (someone@microsoft.com) or type in a sender's display name in quotation marks.
Note The Filter directory is automatically created in the virtual server's directory when the first message is filtered.
