DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email message has been sent by an authorized individual or mail server. A digital signature is added to the email’s header by 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 verify who actually sent it and if its content has been edited in any way. The chief purpose of DKIM is to obstruct the widespread scam and spam emails, as it makes it impossible to forge an email address. If an email message is sent from an address claiming to belong to your bank, for example, but the signature does not match, you will either not get the email message at all, or you will receive it with a warning notice that most likely it’s not a legitimate one. It depends on email service providers what exactly will happen with an email message which fails the signature test. DKIM will also provide you with an additional layer of protection when you communicate with your business allies, for instance, since they can see that all the messages that you send are authentic and have not been meddled with in the meantime.
DomainKeys Identified Mail in Website Hosting
The DomainKeys Identified Mail functionality is pre-enabled for all domain names that are hosted in a website hosting account on our cloud hosting platform, so you will not need to do anything on your end to turn it on. The sole requirement 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 e-mails will go through our mail servers. The private cryptographic key will be created on the server and the TXT record, which includes the public key, will be published to the DNS database automatically, so you will not need to do anything manually on your end in order to enable this functionality. The DKIM authentication system will permit you to send credible e-mail messages, so if you are sending a newsletter or offers to clients, for instance, your email messages will always reach their target audience, whereas unsolicited third parties will not be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DKIM activated by default, so if you select a semi-dedicated server package and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private key on our email servers for the e-signature and a TXT record carrying the public key for the DNS system. As the protection is set up for a specific domain name, all addresses created with it will carry a signature, so you won’t need to worry that the email messages that you send out may not reach their destination email address or that someone may spoof any of your email addresses and try to scam/spam people. This may be very important if you use e-communication in your business, as your colleagues and/or clients will be able to distinguish genuine messages from fake ones.
