DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an e-mail has been sent by an authenticated email server or person. An e-signature is attached to the header of the email message by using a private cryptographic key. When the message is received, a public key that’s available in the global Domain Name System is used to check who exactly sent it and whether the content has been altered in some way. The main purpose of DomainKeys Identified Mail is to impede the widespread spam and scam email messages, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not receive the email at all, or you will get it with a warning that most likely it’s not a legitimate one. It depends on email providers what exactly will happen with an email message that fails to pass the signature test. DKIM will also provide you with an added layer of safety when you communicate with your business allies, for instance, since they can see that all the e-mail messages that you exchange are legitimate and haven’t been tampered with in the meantime.

DomainKeys Identified Mail in Cloud Website Hosting

If you buy any of the Linux cloud website hosting that we offer, the DomainKeys Identified Mail option will be enabled as standard for any domain that you register under your shared website hosting account, so you won’t need to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain will be handled by our cloud platform), a private key will be issued immediately on our mail servers and a TXT record with a public key will be sent to the global Domain Name System. All addresses created using this domain will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target audience and the recipients will be sure that they are legitimate, as the DomainKeys Identified Mail feature makes it impossible for unauthorized individuals to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so if you pick a semi-dedicated package and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private cryptographic key on our mail servers for the digital signature and a TXT record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a specific domain name, all addresses created using it will have a signature, so you won’t have to worry that the email messages that you send out may not reach their target email address or that somebody may forge any of your email addresses and attempt to scam/spam people. This may be really essential if you rely on electronic communication in your business, since your partners and/or clients will be able to distinguish authentic messages from phony ones.
