DomainKeys Identified Mail (DKIM) is a validation system used to certify that an email has been sent by an authorized server or person. An e-signature is attached to the email message’s header by using a private encryption key. When the email message is received, a public key that’s available in the global DNS database is used to validate who exactly sent it and whether the content has been edited in any way. The primary purpose of DKIM is to avert the widely spread scam and spam email messages, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t correspond, you will either not get the message at all, or you will receive it with a notification that most probably it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email that fails the signature check. DomainKeys Identified Mail will also give you an extra layer of safety when you communicate with your business associates, for example, since they can see for themselves that all the e-mails that you send are authentic and have not been manipulated in the meantime.
DomainKeys Identified Mail in Hosting
In case you host a domain in a hosting account from our company, 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 in the Hosted Domains section of the Hepsia Control Panel, on the condition that the domain also uses our NS records. A private cryptographic key will be generated on our mail servers, while a public key will be published to the global DNS database automatically by using the TXT resource record. Thus, you will not need to do anything manually and you will be able to make use of all the benefits of this authentication system – your messages will reach any target destination without being disallowed and no one will be able to send messages faking your e-mail addresses. The latter is very important if the essence of your Internet presence suggests sending periodic newsletters or offers via email to prospective and current customers.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated hosting plans come with DKIM enabled by default, so in case you select a semi-dedicated package and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private key on our mail servers for the e-signature and a TXT resource record carrying the public key for the DNS system. Since the protection is set up for a given domain name, all email addresses created under it will carry a signature, so you will not have to worry that the messages that you send out may not reach their destination email address or that somebody may forge any of your addresses and attempt to scam/spam people. This may be very essential in case you rely on electronic communication in your business, since your associates and/or customers will be able to distinguish genuine messages from spoofed ones.
