DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an e-mail message has been sent by an authenticated email server or person. An electronic signature is attached to the header of the message using a private cryptographic key. When the message is received, a public key that’s available in the global DNS database is used to check who actually sent it and whether its content has been modified in any way. The chief purpose of DomainKeys Identified Mail is to hamper the widely spread scam and spam emails, 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 doesn’t correspond, you will either not receive the email message at all, or you will get it with a warning that most likely it’s not authentic. It depends on email providers what exactly will happen with an email which fails the signature test. DomainKeys Identified Mail will also supply you with an added safety layer when you communicate with your business allies, for example, as they can see that all the e-mail messages that you exchange are authentic and have not been meddled with on their way.
DomainKeys Identified Mail in Hosting
The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a hosting account on our cloud web hosting platform, so you will not need to do anything yourself to turn it on. The only condition is that the particular domain name should be hosted in a website hosting account on our platform using our NS and MX records, so that the e-mails will go through our email servers. The private cryptographic key will be created on the server and the TXT record, which contains the public key, will be published to the DNS database automatically, so you won’t have to do anything manually on your end in order to activate this feature. The DKIM email validation system will permit you to send credible messages, so if you’re sending a newsletter or offers to customers, for example, your emails will always reach their target destination, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
If you pick any of the Linux semi-dedicated hosting that we are offering, you will be able to use the DKIM option with any domain that you register through your new account without any manual setup, as our avant-garde cloud hosting platform will set up all the needed records automatically, provided that the domain uses our name servers. The aforementioned is required for a TXT resource record to be set up for the domain name, as this is how the public cryptographic key can become available in the global DNS database. The private key will also be added automatically to our email servers, so anytime you send a new message, it will carry our system’s electronic signature. The number of spam email messages keeps growing every year and very often false addresses are used, but when you make use of our hosting services, you and your customers or colleagues won’t have to worry about that.
