DomainKeys Identified Mail (DKIM) is a validation system used to prove that an e-mail has been sent by an authorized individual or email server. A digital signature is attached to the header of the email using a private encryption key. When the email is received, a public key that is available in the global DNS database is used to confirm who actually sent it and whether its content has been changed in some way. The prime purpose of DomainKeys Identified Mail is to hamper the widely spread scam and spam emails, as it makes it impossible to forge an email address. If an email 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 receive the email message at all, or you will get it with a warning notification that most likely it is not a legitimate one. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature test. DKIM will also supply you with an additional layer of protection when you communicate with your business associates, for example, as they can see that all the email messages that you exchange are legitimate and haven’t been tampered with in the meantime.
DomainKeys Identified Mail in Cloud Hosting
If you buy one of the Linux cloud packages
that we are offering, the DomainKeys Identified Mail feature will be enabled as standard for any domain that you register under your account, so you won’t need to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain name will be handled by our cloud platform), a private encryption key will be created right away on our mail servers and a TXT record with a public key will be sent to the Domain Name System. All addresses set up with this domain name will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target destination and the recipients will be sure that the messages are legitimate, since the DomainKeys Identified Mail feature makes it impossible for unauthorized persons to forge your addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated packages
come with DomainKeys Identified Mail 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 email validation system will be set up automatically – a private encryption key on our email servers for the electronic signature and a TXT record carrying the public key for the DNS system. Since the protection is set up for a specific domain name, all e-mail addresses created with it will carry a signature, so you will not have to worry that the email messages that you send out may not reach their destination email address or that somebody may spoof any of your email addresses and attempt to scam/spam people. This may be rather important in case you use electronic communication in your business, as your colleagues and/or customers will be able to distinguish genuine messages from counterfeit ones.
