DKIM

What is DKIM

For technology for enhancing the credibility of emails, which helps detection of spurious reports. The message sent by the SMTP server is signed with the private key of the sender domain. This signature is stored in the email header. Server recipient compares this signature with a public key stored in the DNS domain records. That the signature matches is shown that email actually came from the sender's domain, and that during the transmission of a message not to adjust it.

How DKIM works and conditions of use

DKIM technology comes from Cisco and Yahoo, and does not interfere with existing email system - is fully compatible with it. The report reflected only the addition of DKIM-Signature header, which contains the electronic signature generated by the sender's SMTP server. DKIM does not impose any requirements on end users and compared, for example, an electronic signature is not needed Install the private key, or its function may not support client sender and recipient. In the case of DKIM end user therefore does not need to set anything and install.
