DomainKeys Identified Mail, or DKIM, is a method for checking the genuineness of an email by using a digital signature. When DKIM is activated for a given domain, a public encryption key is published to the global DNS system and a private one is stored on the mail server. If a new message is sent, a signature is issued using the private key and when the email message is delivered, that signature is verified by the incoming mail server using the public key. In this way, the receiver can easily recognize if the message is genuine or if the sender’s address has been forged. A mismatch will occur if the content of the email message has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received email messages are identical and that nothing has been added or deleted. This authentication system will increase your email security, as you can confirm the genuineness of the important emails that you get and your colleagues can do the same with the email messages that you send them. Depending on the given mail service provider’s policy, an email message that fails to pass the examination may be removed or may reach the receiver’s inbox with a warning flag.

DomainKeys Identified Mail in Cloud Hosting

If you order one of the Linux cloud hosting that we offer, the DomainKeys Identified Mail option will be activated as standard for any domain that you add to your shard hosting account, so you won’t have to create any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain will be handled by our cloud hosting platform), a private cryptographic key will be issued straight away on our mail servers and a TXT resource record with a public key will be sent to the DNS database. All email addresses set up using this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target audience and the recipients will know that the messages are genuine, as the DomainKeys Identified Mail functionality makes it impossible for unsolicited persons to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

If you pick one of the semi-dedicated servers that we are offering, you will be able to use the DKIM option with any domain name that you add to your new semi-dedicated hosting account without any manual setup, as our high-tech cloud hosting platform will create all the compulsory records automatically, provided that the domain uses our name servers. The latter is required for a TXT record to be created for the domain, as this is how the public cryptographic key can become available in the global Domain Name System. The private key will also be added automatically to our email servers, so every time you send a new email, it will have our system’s electronic signature. The number of unsolicited bulk messages keeps increasing each year and rather often fake email addresses are used, but when you make use of our web hosting services, you and your customers or associates will not need to bother about that.
