Challenge / Response (C/R) Spam Filtering
A feature to send a reply email automatically with a challenge to unknown senders. The sender is asked to perform some action to assure delivery of the original message, which would otherwise not be delivered. Senders that have previously performed the challenging action would be automatically whitelisted.

Ignore the SPF Whitelist Test Exception for the Recipient Whitelist
Option to exclude the Recipient Whitelist from the scope of the SPF Whitelist Test Exception (but still apply the exception for other whitelists), so the recipient would be whitelisted in all cases, even if the SPF test is enabled to run on whitelisted emails.

Whitelist Senders on SPF Pass Only
Option to whitelist the sender only if it is whitelisted by the Sender Whitelist and explicitly passes the SPF test (so the email will not get whitelisted on SoftFail, Neutral and Fail). If enabled, this would override the SPF Whitelist Test Exception setting.
