DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an email message has been sent by an authorized mail server or individual. An e-signature is added to the header of the message using a private key. When the message is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and whether the content has been changed in some way. The primary purpose of DomainKeys Identified Mail is to obstruct the widely spread 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, for example, but the signature does not match, you will either not get the email message at all, or you’ll get it with a warning note that most probably it’s not authentic. It depends on mail service providers what exactly will happen with an email which fails to pass the signature test. DomainKeys Identified Mail will also provide you with an extra protection layer when you communicate with your business partners, for instance, as they can see that all the email messages that you exchange are genuine and have not been manipulated on their way.

DomainKeys Identified Mail in Shared Web Hosting

The DomainKeys Identified Mail functionality is activated by default for all domain names that are hosted in a shared web hosting account on our cloud servers, so you will not need to do anything on your end to activate it. The only condition is that the given domain should be hosted in an account on our platform using our MX and NS resource records, so that the email messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT resource record, which contains the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to enable this feature. The DKIM authentication system will permit you to send out credible e-mail messages, so if you are sending a newsletter or offers to clients, for instance, your emails will always reach their target destination, whereas unsolicited 3rd parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

When you choose one of the Linux semi-dedicated hosting offered by our company, you will be able to use the DKIM option with any domain that you register through your brand-new semi-dedicated hosting account without any manual intervention, as our advanced cloud hosting platform will create all the obligatory records automatically, provided that the domain name uses our name servers. The latter is required for a TXT resource record to be set up for the domain name, since this is how the public encryption key can become available in the global DNS database. The private key will also be added automatically to our email servers, so every time you send a new email message, it will carry our system’s e-signature. The number of spam emails continues to increase each year and very frequently bogus email addresses are used, but if you use our hosting services, you and your clients or partners will not need to worry about that.
