Bad/Good List

Mail From Filter

The Mail From Filter under SMTP Setup allows the administrator to enter domains to be restricted. If you prefer to filter by IP address, use the Access Control tab under Service Parameter Setup (Services option).

Note: To determine the actual addresses to be listed in each box, analyze addresses from the System Log/SMTP. Do not automatically include addresses in mail headers, because the sender's address in the header may differ from the actual origin of the message.
