Using Safelists and Blocklists to Control Email Delivery Based on Sender

Administrators and end users can use safelists and blocklists to help determine which messages are spam. Safelists specify senders and domains that are never treated as spam. Blocklists specify senders and domains that are always treated as spam.

You can allow end users (email users) to manage the safelist and blocklist for their own email accounts. For example, an end user may receive email from a mailing list that no longer interests him. He may decide to add this sender to his blocklist to prevent emails from the mailing list from being sent to his inbox. On the other hand, end users may find that emails from specific senders are sent to their spam quarantine when they do not want them to be treated as spam. To ensure that messages from these senders are not quarantined, they may want to add the senders to their safelists.

Changes that end users and administrators make are visible to and can be changed by either.
