DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an email message has been sent by an authorized email server or person. An e-signature is attached to the header of the email by using a private cryptographic key. When the email message is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and if the content has been changed in some way. The fundamental purpose of DKIM is to prevent the widely spread scam and spam emails, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t match, you will either not get the email at all, or you’ll get it with a warning alert that most probably it is not legitimate. It depends on email providers what exactly will happen with an email message which fails to pass the signature test. DKIM will also provide you with an added layer of safety when you communicate with your business allies, for example, since they can see for themselves that all the messages that you send are authentic and have not been modified on their way.

DomainKeys Identified Mail in Web Hosting

When you purchase one of the Linux web hosting that we offer, the DomainKeys Identified Mail option will be activated by default for any domain that you add to your shard hosting account, so you won’t need to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain name will be handled by our cloud hosting platform), a private key will be issued instantaneously on our mail servers and a TXT resource record with a public key will be sent to the Domain Name System. All addresses set up with this domain will be protected by DKIM, so if you send out email messages such as periodic newsletters, they will reach their target destination and the receivers will be sure that the messages are authentic, since the DomainKeys Identified Mail option makes it impossible for unsolicited individuals to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail activated by default, so if you pick a semi-dedicated plan and you add a domain using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a certain domain name, all email addresses created using it will have a signature, so you will not need to worry that the email messages that you send out may not be delivered to their target email address or that someone may fake any of your addresses and try to scam/spam people. This may be very important in case you rely on electronic communication in your business, as your colleagues and/or customers will be able to distinguish legitimate email messages from spoofed ones.
