A DKIM signature for outgoing messages is a digital signature added to messages sent from email addresses of a certain domain for purposes of identifying users by the name of the corporate domain.
The DomainKeys Identified Mail (DKIM) technology lets the user verify that the message was indeed sent from the declared domain. The DKIM technology aims to combat forged sender addresses that are often used in phishing messages and mail spam. Instead of the traditional IP address, DKIM identifies the sender using a digital signature associated with the name of the corporate domain. The signature is automatically checked by the recipient. Senders are authenticated using the domain name system (DNS), which allows sending public encryption keys.
You can configure adding a DKIM signature to messages in the web interface of KSMG. Configuration involves the following steps:
- Creating or importing a DKIM key.
- Retrieving a DNS record for a public DKIM key.
- Adding the retrieved DNS record to the settings of your DNS server.
