DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an email has been sent by an authenticated mail server or individual. A digital signature is attached to the header of the message by using a private key. When the message is received, a public key that is available in the global DNS database is used to check who actually sent it and whether its content has been changed in some way. The fundamental task of DomainKeys Identified Mail is to hinder the widespread spam and scam email messages, 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 does not match, you will either not receive the message at all, or you will get it with a warning notice that most likely it is not an authentic one. It depends on mail service providers what exactly will happen with an email message that fails the signature test. DKIM will also give you an extra protection layer when you communicate with your business associates, for instance, since they can see that all the e-mails that you exchange are legitimate and haven’t been meddled with on their way.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail functionality is pre-enabled for all domain names that are hosted in a web hosting account on our cloud servers, so you won’t have to do anything yourself to activate it. The only condition is that the particular domain should be hosted in a website hosting account on our platform using our MX and NS resource records, so that the e-mails will go through our email servers. The private encryption key will be generated on the server and the TXT record, which contains the public key, will be published to the DNS system automatically, so you will not need to do anything manually on your end in order to activate this feature. The DomainKeys Identified Mail email validation system will permit you to send out trustable emails, so if you’re sending offers or a newsletter to clients, for instance, your emails will always reach their target viewers, while unsolicited third parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DKIM enabled by default, so in case you pick a semi-dedicated server package and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private encryption key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the Domain Name System. Since the DKIM protection is set up for a given domain, all addresses created using it will carry a signature, so you won’t have to worry that the email messages that you send out may not be delivered to their target address or that someone may fake any of your addresses and try to spam/scam people. This may be really important in case you use email communication in your business, as your colleagues and/or customers will be able to distinguish legitimate email messages from phony ones.
