DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email authentication system, which prevents email headers from being forged and email content from being meddled with. This is done by attaching an e-signature to every message sent from an address under a certain domain. The signature is issued on the basis of a private key that’s available on the SMTP server and it can be validated using a public key, which is available in the global DNS database. In this way, any email with altered content or a spoofed sender can be recognized by mail service providers. This approach will heighten your online security noticeably and you will know for sure that any email sent from a business partner, a banking institution, etc., is authentic. When you send email messages, the recipient will also know for sure that you are indeed the one who has sent them. Any email that appears to be fake may either be flagged as such or may never reach the recipient’s inbox, depending on how the given provider has chosen to deal with such emails.
DomainKeys Identified Mail in Shared Hosting
When you order any of the Linux shared service that we’re offering, the DomainKeys Identified Mail functionality will be activated by default for any domain name that you add to your website hosting account, so you will not have to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain will be handled by our cloud platform), a private encryption key will be created straight away on our mail servers and a TXT resource record with a public key will be sent to the global DNS database. All email addresses created using this domain will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that they are genuine, as the DomainKeys Identified Mail feature makes it impossible for unauthorized people to spoof your addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DomainKeys Identified Mail enabled by default, so if you pick a semi-dedicated plan and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private cryptographic key on our mail servers for the e-signature and a TXT resource record carrying the public key for the DNS database. Since the protection is set up for a particular domain name, all addresses created using it will have a signature, so you won’t have to worry that the messages that you send out may not reach their target address or that somebody may spoof any of your addresses and try to spam/scam people. This may be quite essential if you rely on email communication in your business, as your colleagues and/or clients will be able to distinguish real emails from forged ones.
