Step 3
Authorized Sender Filtering
Authorized Sender Filtering (Challenge-Response) is the most effective Spam filtering concept known today.
Challenge-Response works on concept of Authorized List which allows mails only from authorized senders or senders who verify themselves. Any
mails from unknown senders are quarantined on SpamBlocks server & awaits authorization.
Authorization can be done by sender (by clicking on
verification link from challenge-response mail), user or administrator from Web based Control Panel or with SpamBlocks DeskLite (Windows Desktop based utility).
Upon authorization, mails are immediately delivered to your mailbox and senders are added to your authorized list. Henceforth, any emails from
Authorized senders (or domains) will always get delivered to your mailbox without requiring any further authorization.
Group Authorization :
With Group Authorization enabled (corporate solutions only), sender authorization is done against
combined authorized list of entire group.
