DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an e-mail message has been sent by an authorized person or server. An electronic signature is attached to the message’s header by using a private encryption key. When the email is received, a public key that’s available in the global Domain Name System is used to verify who exactly sent it and whether the content has been changed in any way. The prime purpose of DomainKeys Identified Mail is to impede the widespread spam and scam email messages, 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 or financial institution, for instance, but the signature does not match, you will either not get the message at all, or you will get it with a warning notification that most probably it is not a genuine one. It depends on email providers what exactly will happen with an email message that fails the signature test. DomainKeys Identified Mail will also offer you an additional security layer when you communicate with your business allies, for instance, since they can see for themselves that all the messages that you send are legitimate and haven’t been tampered with in the meantime.
DomainKeys Identified Mail in Shared Hosting
When you buy one of the Linux shared hosting packages that we’re offering, the DomainKeys Identified Mail feature will be activated as standard for any domain name that you add to your hosting account, so you won’t 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 developed Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be issued right away on our email servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses set up using this domain will be protected by DKIM, so if you send email messages such as periodic newsletters, they will reach their target destination and the receivers will know that the messages are legitimate, since the DKIM option makes it impossible for unauthorized persons to spoof your addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting packages come with DomainKeys Identified Mail activated by default, so if you pick a semi-dedicated hosting plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the authentication system will be set up automatically – a private encryption key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS database. As the DKIM protection is set up for a particular domain, all e-mail addresses created using it will have a signature, so you will not need to worry that the email messages that you send out may not reach their target email address or that somebody may forge any of your addresses and try to spam/scam people. This may be really essential when you use email communication in your business, as your colleagues and/or clients will be able to distinguish authentic email messages from spoofed ones.
