DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an email has been sent by an authorized person or server. An electronic signature is attached to the header of the message by using a private key. When the message is received, a public key that is available in the global DNS database is used to validate who actually sent it and if the content has been altered in some way. The essential purpose of DKIM is to obstruct the widespread spam and scam emails, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not correspond, you will either not get the email message at all, or you will get it with a warning note that most probably it’s not an authentic one. It depends on email service providers what exactly will happen with an email message that fails to pass the signature test. DomainKeys Identified Mail will also give you an added security layer when you communicate with your business associates, for instance, since they can see that all the email messages that you send are genuine and haven’t been meddled with on their way.
DomainKeys Identified Mail in Shared Hosting
If you obtain one of the Linux shared hosting packages
that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain that you register under your website hosting account, so you will not need to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain name will be handled by our cloud hosting platform), a private encryption key will be issued straight away on our email servers and a TXT resource record with a public key will be sent to the DNS system. All addresses set up using this domain name will be protected by DKIM, so if you send email messages such as regular newsletters, they will reach their target destination and the recipients will be sure that the messages are authentic, as the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated packages
come with DomainKeys Identified Mail enabled by default, so in case you choose a semi-dedicated hosting package and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private encryption key on our email servers for the electronic signature and a TXT resource record carrying the public key for the global DNS system. As the protection is set up for a particular domain name, all e-mail addresses created under it will carry a signature, so you won’t need to worry that the email messages that you send may not be delivered to their destination email address or that somebody may spoof any of your email addresses and try to spam/scam people. This may be really important when you use e-communication in your business, as your colleagues and/or customers will be able to distinguish genuine email messages from fake ones.
