DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email message by using an electronic signature. When DomainKeys Identified Mail is enabled for a specific domain name, a public cryptographic key is published to the global DNS database and a private one is stored on the email server. When a new email is sent, a signature is generated using the private key and when the email is received, that signature is checked by the POP3/IMAP mail server using the public key. Thus, the receiver can easily recognize if the email is legitimate or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email message has been edited in the meantime as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or deleted. This email validation system will strengthen your email safety, since you can confirm the genuineness of the important email messages that you receive and your associates can do the exact same thing with the email messages that you send them. Depending on the particular email provider’s policy, a message that fails to pass the check may be erased or may emerge in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Website Hosting

The DomainKeys Identified Mail option is pre-enabled for all domain names that are hosted in a shared website hosting account on our cloud platform, so you won’t have to do anything on your end to activate it. The sole requirement is that the given domain should be hosted in a hosting account on our platform using our NS and MX resource records, so that the e-mail messages will go through our email servers. The private cryptographic key will be created on the server and the TXT resource record, which contains the public key, will be published to the global Domain Name System automatically, so you will not have to do anything manually on your end in order to activate this option. The DKIM email validation system will permit you to send trustable messages, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, whereas unauthorized 3rd parties won’t be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DKIM activated by default, so if you select this type of hosting and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. Since the DKIM protection is set up for a certain domain name, all e-mail addresses created under it will have a signature, so you will not have to worry that the emails that you send out may not be delivered to their target email address or that someone may fake any of your email addresses and try to scam/spam people. This may be extremely essential if you rely on email communication in your business, since your partners and/or customers will be able to distinguish legitimate messages from spoofed ones.
