DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an email has been sent by an authorized mail server or person. An electronic signature is added to the email message’s header using a private key. When the email is received, a public key that is available in the global Domain Name System is used to check who actually sent it and whether the content has been altered in some way. The prime function of DKIM is to block the widely spread scam and spam 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 example, but the signature does not match, you will either not receive the email at all, or you’ll receive it with a warning alert that most probably it’s not authentic. It depends on email providers what exactly will happen with an email message that fails to pass the signature test. DKIM will also supply you with an extra protection layer when you communicate with your business associates, for example, since they can see for themselves that all the messages that you exchange are legitimate and haven’t been tampered with on their way.
DomainKeys Identified Mail in Shared Web Hosting
The DomainKeys Identified Mail functionality is pre-enabled for all domains that are hosted in a shared web hosting account on our cloud servers, so you won’t need to do anything on your end to turn it on. The only condition is that the given domain should be hosted in a web hosting account on our end using our MX and NS resource records, so that the emails will go through our email servers. The private key will be created on the server and the TXT resource record, which includes the public key, will be published to the global Domain Name System automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail validation system will permit you to send out trustable email messages, so if you’re sending offers or a newsletter to customers, for instance, your email messages will always reach their target destination, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting come with DomainKeys Identified Mail enabled by default, so if you select a semi-dedicated package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private encryption key on our email servers for the digital signature and a TXT resource record carrying the public key for the DNS database. Since the DKIM protection is set up for a given domain, all e-mail addresses created using it will carry a signature, so you won’t need to worry that the email messages that you send may not reach their target address or that someone may spoof any of your addresses and try to spam/scam people. This may be really essential in case you rely on e-communication in your business, since your colleagues and/or customers will be able to distinguish real emails from false ones.
