DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email message using an e-signature. When DomainKeys Identified Mail is activated for a certain domain name, a public key is published to the global Domain Name System and a private one is stored on the email server. If a new email is sent, a signature is generated using the private key and when the message is delivered, that signature is authenticated by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily distinguish if the email is authentic or if the sender’s email address has been forged. A discrepancy will occur if the content of the email message has been altered on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or erased. This authentication system will strengthen your email safety, since you can verify the genuineness of the important emails that you receive and your colleagues can do the exact same thing with the messages that you send them. Depending on the given email service provider’s adopted policies, a message that fails the check may be removed or may appear in the recipient’s mailbox with a warning symbol.

DomainKeys Identified Mail in Website Hosting

If you purchase one of the Linux website hosting packages that we’re offering, the DomainKeys Identified Mail option will be activated as standard for any domain name that you add to your shared account, so you will not have to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our NS and MX records (so that the emails associated with this domain will be handled by our cloud platform), a private cryptographic key will be generated right away on our mail servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as regular newsletters, they will reach their target audience and the receivers will be sure that the messages are authentic, as the DomainKeys Identified Mail functionality makes it impossible for unauthorized people to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated hosting come with DKIM enabled by default, so in case you select a semi-dedicated server package and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the authentication system will be created automatically – a private cryptographic key on our mail servers for the e-signature and a TXT resource record carrying the public key for the global DNS database. Since the protection is set up for a given domain, all e-mail addresses created under it will have a signature, so you won’t need to worry that the email messages that you send out may not reach their destination address or that someone may fake any of your addresses and attempt to scam/spam people. This may be very important if you rely on e-communication in your business, as your partners and/or clients will be able to distinguish authentic emails from phony ones.
