Callback verification
:''For the "callback verifier" software once commonly used by dial-up bulletin board systems, see Callback (telecommunications)#Modem security.''
Callback verification, also known as callout verification or Sender Address Verification, is a technique used by SMTP software in order to validate e-mail addresses. The most common target of verification is the sender address from the message envelope (the address specified during the SMTP dialogue as "MAIL FROM"). It is mostly used as an anti-spam measure.
==Purpose==
Since a large percentage of e-mail spam is generated from a forged sender ("mfrom") addresses, some spam can be detected by checking whether forging resulted in an invalid address, using this method.
A related technique is "call forwards", in which a secondary or firewall mail exchanger can verify recipients at the primary mail exchanger for the domain in order to decide whether the address is deliverable.
