DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email has been sent by an authorized server or person. A digital signature is attached to the header of the email by using a private encryption key. When the email message is received, a public key that’s available in the global DNS database is used to check who actually sent it and if the content has been changed in some way. The essential purpose of DKIM is to hamper the widely spread spam and scam emails, as it makes it impossible to forge an email address. If an email message is sent from an address claiming to belong to your bank, for example, but the signature doesn’t match, you will either not receive the email message at all, or you will receive it with a warning notification that most likely it’s not authentic. It depends on mail service providers what exactly will happen with an email that fails the signature check. DomainKeys Identified Mail will also supply you with an extra security layer when you communicate with your business partners, for example, as they can see that all the messages that you send are genuine and have not been meddled with on their way.

DomainKeys Identified Mail in Shared Hosting

If you buy any of the shared hosting plans that we offer, the DomainKeys Identified Mail functionality will be enabled by default for any domain name that you add to your website hosting account, so you will not need to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain will be handled by our cloud platform), a private key will be issued straight away on our mail servers and a TXT resource record with a public key will be sent to the Domain Name System. All addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are legitimate, because the DomainKeys Identified Mail functionality makes it impossible for unauthorized people to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail enabled by default, so in case you opt for a semi-dedicated plan and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private encryption key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global DNS system. Since the protection is set up for a certain domain, all email addresses created using it will carry a signature, so you will not have to worry that the messages that you send may not reach their target email address or that somebody may fake any of your addresses and try to scam/spam people. This may be quite important when you use e-communication in your business, as your partners and/or clients will be able to distinguish authentic messages from counterfeit ones.
