DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an email message has been sent by an authenticated mail server or person. An e-signature is attached to the header of the email message by using a private key. When the message is received, a public key that’s available in the global DNS database is used to check who exactly sent it and if the content has been changed in some way. The chief purpose of DKIM is to block the widely spread spam and scam emails, as it makes it impossible to forge an email address. If a message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t match, you will either not get the message at all, or you will get it with a warning note that most probably it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature check. DKIM will also give you an added security layer when you communicate with your business allies, for instance, since they can see for themselves that all the messages that you send are legitimate and have not been tampered with in the meantime.
DomainKeys Identified Mail in Shared Hosting
If you purchase one of the Linux shared packages
that we are offering, the DomainKeys Identified Mail option will be enabled as standard for any domain name that you add to your web hosting account, so you will not need to set up 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 MX and NS records (so that the emails associated with this domain will be handled by our cloud platform), a private cryptographic key will be generated immediately on our email servers and a TXT record with a public key will be sent to the global Domain Name System. All addresses set up using this domain name will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target audience and the receivers will be sure that they are legitimate, as the DomainKeys Identified Mail functionality makes it impossible for unsolicited individuals to forge your e-mail addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
The DomainKeys Identified Mail functionality is included by default with any domain name that’s added to a semi-dedicated server
account with us. It should also use our name servers, so that its DNS records are handled by our platform. The latter makes it possible for a special TXT record to be created, which is in fact the public encryption key that verifies if a given email message is authentic or not. This record is created once a domain name is added to a semi-dedicated account through the Hepsia Control Panel and at the same time, a private key is generated on our email servers. If you use our email and web hosting services, your emails will always reach their target readers and you will not need to worry about unsolicited people forging your addresses for spamming or scamming purposes, which is something rather important if you use email messages to communicate with your business allies.
