DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an email message has been sent by an authorized person or email server. A digital signature is attached to the email message’s header by using a private key. When the email message is received, a public key that’s available in the global DNS database is used to check who exactly sent it and whether the content has been changed in some way. The fundamental function of DKIM is to prevent the widely spread scam and spam emails, as it makes it impossible to fake 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 message at all, or you’ll receive it with a warning alert that most probably it is not a genuine one. It depends on mail service providers what exactly will happen with an email that fails to pass the signature check. DKIM will also supply you with an extra security layer when you communicate with your business partners, for instance, since they can see that all the e-mails that you send are authentic and haven’t been tampered with on their way.
DomainKeys Identified Mail in Cloud Website Hosting
The DomainKeys Identified Mail feature is activated by default for all domain names that are hosted in a cloud website hosting
account on our cloud hosting platform, so you will not have to do anything on your end to enable it. The only condition is that the given domain name should be hosted in a website hosting account on our platform using our NS and MX records, so that the email messages will go through our email servers. The private cryptographic key will be created on the server and the TXT resource record, which includes the public key, will be published to the global DNS database automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail authentication system will permit you to send out trustable emails, so if you’re sending a newsletter or offers to clients, for example, your email messages will always reach their target audience, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated servers
come with DKIM activated by default, so if you opt for a semi-dedicated server plan 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 mail servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. As the protection is set up for a certain domain, all e-mail addresses created with it will have a signature, so you won’t need to worry that the messages that you send may not reach their destination address or that somebody may forge any of your email addresses and try to scam/spam people. This may be quite essential if you use electronic communication in your business, as your associates and/or customers will be able to distinguish genuine email messages from counterfeit ones.
