DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email using an e-signature. When DomainKeys Identified Mail is activated for a given domain, a public encryption key is published to the global DNS system and a private one is kept on the email server. If a new message is sent, a signature is generated using the private key and when the message is received, that signature is authenticated by the POP3/IMAP server using the public key. In this way, the receiver can easily distinguish if the email message is authentic or if the sender’s email address has been forged. A discrepancy will occur if the content of the email has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or deleted. This validation system will increase your email security, as you can confirm the legitimacy of the important emails that you get and your colleagues can do likewise with the email messages that you send them. Depending on the particular mail service provider’s policy, an email that fails to pass the check may be erased or may emerge in the receiver’s mailbox with a warning flag.

DomainKeys Identified Mail in Shared Web Hosting

The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a shared web hosting account on our cloud website hosting platform, so you won’t need to do anything on your end to turn it on. The sole condition is that the given domain name should be hosted in a hosting account on our end using our NS and MX records, so that the email messages will go through our email servers. The private key will be created on the server and the TXT record, which includes the public key, will be published to the global DNS system automatically, so you will not need to do anything manually on your end in order to activate this functionality. The DomainKeys Identified Mail authentication system will permit you to send out trustworthy e-mails, so if you are sending a newsletter or offers to customers, for example, your email messages will always reach their target destination, while unauthorized third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you choose a semi-dedicated plan and you add a domain using our name servers via your Hepsia Control Panel, the records required for the validation system will be set up automatically – a private encryption key on our mail servers for the e-signature and a TXT record carrying the public key for the global DNS database. Since the DKIM protection is set up for a certain domain, all email addresses created with it will have a signature, so you won’t need to worry that the email messages that you send out may not reach their target email address or that someone may fake any of your email addresses and attempt to spam/scam people. This may be quite essential if you rely on email communication in your business, since your associates and/or clients will be able to distinguish real emails from false ones.
