DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an e-mail message has been sent by an authorized server or individual. A digital signature is attached to the header of the email using a private encryption key. When the email message is received, a public key that is available in the global Domain Name System is used to check who exactly sent it and if the content has been altered in some way. The primary function of DKIM is to impede the widespread spam and scam messages, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t match, you will either not get the email message at all, or you will get it with an alert that most probably it is not legitimate. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also offer you an added protection layer when you communicate with your business allies, for instance, since they can see that all the emails that you exchange are legitimate and haven’t been modified on their way.

DomainKeys Identified Mail in Shared Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a shared hosting account on our cloud hosting platform, so you will not need to do anything yourself to turn it on. The sole requirement is that the given domain name should be hosted in a website hosting account on our end using our NS and MX 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 global DNS system automatically, so you won’t have to do anything manually on your end in order to activate this option. The DomainKeys Identified Mail email authentication system will allow you to send trustworthy emails, so if you are sending offers or a newsletter to customers, for instance, your email messages will always reach their target audience, whereas unsolicited third parties will not be able to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DKIM enabled by default, so in case you pick a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private key on our mail servers for the digital signature and a TXT record carrying the public key for the Domain Name System. Since the DKIM protection is set up for a given domain, all e-mail addresses created with it will have 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 somebody may spoof any of your email addresses and try to spam/scam people. This may be very essential when you use electronic communication in your business, as your partners and/or customers will be able to distinguish authentic emails from false ones.
