DomainKeys Identified Mail (DKIM) is a validation system used to certify that an email has been sent by an authorized person or server. An electronic signature is attached to the email’s header using a private key. When the email is received, a public key that is available in the global DNS database is used to validate who exactly sent it and whether its content has been modified in any way. The main task of DomainKeys Identified Mail is to stop the widespread spam and scam messages, as it makes it impossible to forge an email address. If a message is sent from an email address claiming to belong to your bank, for instance, but the signature doesn’t match, you will either not receive the message at all, or you’ll get it with a warning that most likely it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature examination. DKIM will also provide you with an added safety layer when you communicate with your business allies, for example, as they can see that all the messages that you exchange are genuine and have not been modified in the meantime.

DomainKeys Identified Mail in Shared Hosting

If you host a domain in a shared hosting account with us, all the obligatory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen as soon as you add the domain name in , provided that the domain also uses our NS resource records. A private key will be generated on our mail servers, whereas a public key will be published to the Domain Name System automatically by using the TXT record. Thus, you won’t have to do anything manually and you’ll be able to take advantage of all the benefits of this email validation system – your messages will reach any target destination without being rejected and nobody will be able to send out messages faking your e-mail addresses. The latter is truly important if the type of your online presence suggests sending regular newsletters or offers via email to prospective and existing customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting packages come with DKIM activated by default, so if you opt for this type of hosting and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS database. As the DKIM protection is set up for a particular domain, all e-mail addresses created with it will have a signature, so you will not have to worry that the email messages that you send out may not be delivered to their destination email address or that someone may forge any of your addresses and try to scam/spam people. This may be quite important in case you use email communication in your business, since your partners and/or clients will be able to distinguish real emails from spoofed ones.
