DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email has been sent by an authorized person or email server. 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 confirm who exactly sent it and if its content has been changed in some way. The prime task of DKIM is to obstruct the widely spread scam and spam emails, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not get the email at all, or you’ll receive it with a warning notice that most probably it is not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails to pass the signature examination. DKIM will also provide you with an extra security layer when you communicate with your business associates, for instance, as they can see that all the e-mails that you send are genuine and haven’t been modified in the meantime.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail option is enabled by default for all domains that are hosted in a website hosting account on our cloud web hosting platform, so you will not have to do anything yourself to activate it. The sole condition is that the particular domain name should be hosted in a hosting account on our end using our NS and MX resource 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 resource record, which contains the public key, will be published to the global Domain Name System automatically, so you won’t need to do anything manually on your end in order to activate this feature. The DKIM validation system will permit you to send out trustable emails, so if you are sending a newsletter or offers to clients, for example, your emails will always reach their target destination, while unauthorized third parties will not be able to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so in case you select this type of hosting and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private key on our mail servers for the e-signature and a TXT record carrying the public key for the global DNS database. As the protection is set up for a particular domain, all addresses created under it will carry a signature, so you will not need to worry that the email messages that you send out may not reach their destination address or that somebody may spoof any of your email addresses and try to spam/scam people. This may be rather important if you use e-communication in your business, since your associates and/or customers will be able to distinguish genuine messages from bogus ones.
