Identity Confirmation

The Axigen Solution: Overview & Architecture

Axigen Identity Confirmation© is basically the implementation of a Challenge / Response-based anti-spam method. It blocks unwanted messages from reaching your users' Inbox by intercepting incoming emails and requiring new senders to confirm their identity, without any effort from your / their part.

The Identity Confirmation system compares the sender of each incoming message against the contents of your Address Book. As a result:

  • If the sender appears in the Address Book, the message comes through, as expected.
  • If the incoming message originates from an unknown address, the Challenge / Response system sends an auto-reply email designed to confirm its authenticity. Once the address in question is verified, the message is delivered appropriately, as are all subsequent messages from the same sender.

Features of the Identity Confirmation:

  • All the received, yet unconfirmed, messages are permanently available for your inspection, without them crowding your users' Inbox, as they are stored in a specific "Unconfirmed Messages" folder.
  • The confirmed senders are automatically added to their "Collected Addresses" contact folder (part of your Address Book).
  • The validation code is at their disposal to change whenever they want to.
  • Users can configure the number of days to be skipped when sending the confirmation request to a sender.

While a Challenge / Response request can be easily fulfilled by a real person, it can hardly be performed by a spammer, on the following grounds:

  • Legitimate senders have a valid return address while spammers usually forge a return address. This means that most spammers won't get the challenge, which results in them automatically failing any required action.
  • Spammers send email in large quantities and would have to perform Challenge / Response actions in large numbers, while legitimate senders would only have to perform them once for every new email contact, at the most.

Even if activated, this mechanism is, of course, not enforced for the users already in the users' Address Book, or present in their Whitelist / Safe senders list.

Should a user want to receive emails from certain automated mass mailing tools (that, naturally, do not posses the ability to fulfill the Challenge / Response request), he / she needs to make sure to add them to their Address Book or Safe senders list, prior to activating the Identity Confirmation system.
