Configure the Approved Senders and Blocked Senders lists to control which email messages Hosted Email Security scans. Specify the senders to allow or block using specific email addresses or entire domains.
For example, *@example.com specifies all senders from the example.com domain.
Evaluation is done in the following order:
End User Quarantine console blocked sender list
Administrator console blocked sender list
End User Quarantine console approved sender list
Administrator console approved sender list
See Sender Filter Order of Evaluation.
IP reputation-based filters use only IP address data to filter messages. You can also use sender email address and domain to filter incoming messages. Approved senders bypass IP reputation-based filtering at the MTA connection level.
Lists of approved or blocked senders are managed using the following screens:
Email messages from senders added to this list are not subject to IP reputation-based, spam, phishing, BEC attack, social engineering attack, Web reputation, or graymail message filtering. Hosted Email Security still performs malware and attachment scanning on all messages received and takes the action configured in policy rules after detecting a malware threat or an attachment policy violation.
