DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email using a digital signature. When DomainKeys Identified Mail is activated for a specific domain name, a public encryption key is published to the global DNS system and a private one is kept on the email server. When a new email message is sent, a signature is generated using the private key and when the email is delivered, that signature is authenticated by the POP3/IMAP mail server using the public key. Thus, the recipient can easily recognize if the email is legitimate or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered messages are identical and that nothing has been attached or deleted. This validation system will enhance your email safety, since you can verify the genuineness of the important email messages that you get and your partners can do the same with the email messages that you send them. Based on the particular email provider’s adopted policies, a message that fails to pass the test may be erased or may be delivered to the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

When you get any of the Linux cloud packages that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you add to your shared web hosting account, so you won’t have to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private key will be created straight away on our mail servers and a TXT resource record with a public key will be sent to the global DNS database. All email addresses created using 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 be sure that they are authentic, since the DKIM option makes it impossible for unauthorized persons to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you pick one of the Linux semi-dedicated hosting packages that we offer, you’ll be able to use the DKIM option with any domain name that you register through your new semi-dedicated server account without any manual intervention, as our avant-garde cloud platform will create all the mandatory records automatically, provided that the domain name uses our name servers. The latter is needed for a TXT resource record to be set up for the domain, as this is how the public key can become available in the global DNS system. The private key will also be added automatically to our mail servers, so every time you send a new email, it will have our system’s digital signature. The number of spam emails keeps increasing every year and very often phony addresses are used, but if you make use of our hosting services, you and your customers or partners won’t have to bother about that.
