Adding Approved Senders

You can add one or more senders to the Approved Senders list. Deep Discovery Email Inspector does not apply sender filtering and sender authentication settings on messages from approved senders.

Important:
  • Deep Discovery Email Inspector does not apply sender filtering and sender authentication settings on messages with IP addresses, domain-resolved IP addresses, or email addresses that match an entry in the Approved Senders list.

  • For SMTP traffic throttling, Deep Discovery Email Inspector checks the senders against the Approved Senders and Blocked Senders lists in the following order:

    • Approved Senders list (IP address)

    • Blocked Senders list (user-defined IP address)

    • SMTP traffic throttling (IP address)

    • Approved Senders list (email address)

    • Blocked Senders list (user-defined email address)

    • SMTP traffic throttling (email address)

Note:

You can add up to 2048 entries to the list.

  1. Go to Administration > Sender Filtering/Authentication > Approved Senders.

    The Approved Senders screen appears.

  2. Click Add.

    The Add Approved Senders screen appears.

  3. Select and configure one of the following:
    • Domain: Select this option to specify the domain of the senders. You can select one or more Resource record types.

      Note:

      Deep Discovery Email Inspector regularly resolves the specified domain, and adds the resolved IP addresses in an entry in the Approved Senders list or updates the resolved IP addresses in the entry.

    • IP address or subnet: Select this option to specify the IPv4/IPv6 address of a sender or the subnet of multiple senders.

    • Email address: Select this option to specify the email address of the sender.

      Tip:

      Deep Discovery Email Inspector support email domains. For example, *@example.com indicates all email addresses in example.com domain.
