Description:
Verifies that a list of approved sender IP addresses is configured.
Why:
Failing to maintain an accurate list of authorized IP addresses may result in spoofed email messages or failure to deliver legitimate messages when SPF is enabled. Maintaining such a list helps ensure that unauthorized servers sending spoofed messages can be detected, and permits message delivery from legitimate senders.
Configured: A list of approved sender IP addresses is configured.
Not Configured: A list of approved sender IP addresses is not configured.
