DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email validation system, which stops email headers from being forged and email content from being modified. This is done by adding a digital signature to every email sent from an address under a particular domain. The signature is issued on the basis of a private cryptographic key that is available on the SMTP server and it can be verified by using a public key, which is available in the global DNS database. In this way, any email message with altered content or a spoofed sender can be spotted by email providers. This approach will enhance your online security greatly and you will know for sure that any e-mail message sent from a business ally, a bank, etc., is an authentic one. When you send out messages, the receiver will also be sure that you are indeed the one who has sent them. Any email that turns out to be counterfeit may either be marked as such or may never show up in the recipient’s inbox, depending on how the given provider has chosen to deal with such email messages.

DomainKeys Identified Mail in Shared Hosting

If you obtain one of the Linux shared hosting that we offer, the DomainKeys Identified Mail option will be enabled as standard for any domain name that you register under your account, so you will not need to create any records or to do anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private encryption key will be created instantly on our mail servers and a TXT resource record with a public key will be sent to the global DNS database. All addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send emails such as regular newsletters, they will reach their target destination and the receivers will be sure that the messages are legitimate, since the DKIM option makes it impossible for unauthorized persons to spoof your e-mail addresses.
