DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email message has been sent by an authorized email server or person. A digital signature is added to the email’s header using a private encryption key. When the email is received, a public key that is available in the global DNS database is used to verify who actually sent it and whether its content has been altered in any way. The primary job of DomainKeys Identified Mail is to block the widespread scam and spam email messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not receive the email message at all, or you will get it with an alert that most likely it’s not legitimate. It depends on email providers what exactly will happen with an email message that fails to pass the signature test. DomainKeys Identified Mail will also provide you with an additional layer of safety when you communicate with your business allies, for example, as they can see that all the e-mails that you exchange are authentic and haven’t been meddled with on their way.

DomainKeys Identified Mail in Shared Hosting

If you buy one of the Linux shared hosting that we offer, the DomainKeys Identified Mail feature will be enabled by default for any domain that you add to your hosting account, so you will not need to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be issued momentarily on our email servers and a TXT record with a public key will be sent to the DNS database. All email addresses created with this domain name will be protected by DKIM, so if you send email messages such as regular newsletters, they will reach their target audience and the receivers will know that the messages are legitimate, because the DomainKeys Identified Mail feature makes it impossible for unauthorized parties to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

The DomainKeys Identified Mail feature is offered by default with any domain that’s registered through a semi-dedicated server account with us. It must also use our name servers, so that its DNS resource records are managed by our platform. The latter makes it possible for a special TXT record to be created, which is in fact the public cryptographic key that verifies if a given email message is genuine or not. Such a record is created once a domain is registered in a semi-dedicated account through the Hepsia Control Panel and at the same time, a private key is generated on our mail servers. If you make use of our email and web hosting services, your messages will always reach their target destination and you will not have to worry about unsolicited individuals using your addresses for spamming or scamming purposes, which is something pretty important in case you use emails to get in touch with your business associates.
