DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an email has been sent by an authorized individual or server. A digital signature is added to the header of the message by using a private key. When the message is received, a public key that’s available in the global Domain Name System is used to validate who actually sent it and whether its content has been modified in any way. The chief job of DKIM is to hamper the widely spread spam and scam email messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not match, you will either not get the email message at all, or you’ll get it with a notification that most likely it is not a legitimate one. It depends on email providers what exactly will happen with an email that fails to pass the signature test. DKIM will also supply you with an added security layer when you communicate with your business allies, for example, since they can see for themselves that all the e-mails that you exchange are authentic and have not been tampered with on their way.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a web hosting account on our cloud hosting platform, so you will not need to do anything yourself to turn it on. The sole condition is that the particular domain name should be hosted in a hosting account on our end using our NS and MX resource records, so that the emails will go through our mail servers. The private encryption key will be generated on the server and the TXT resource record, which contains the public key, will be published to the global DNS database automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DKIM email validation system will permit you to send out trustable e-mail messages, so if you’re sending a newsletter or offers to clients, for instance, your email messages will always reach their target destination, whereas unauthorized third parties won’t be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated service come with DomainKeys Identified Mail activated by default, so in case you select a semi-dedicated server package and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private cryptographic key on our mail servers for the e-signature and a TXT record carrying the public key for the global DNS database. Since the protection is set up for a certain domain, all email addresses created using it will carry a signature, so you will not need to worry that the emails that you send may not reach their destination email address or that someone may spoof any of your email addresses and try to spam/scam people. This may be extremely essential if you rely on electronic communication in your business, as your associates and/or customers will be able to distinguish real messages from phony ones.
