DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email has been sent by an authenticated individual or server. An e-signature is added to the header of the email message using a private cryptographic key. When the message is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and whether the content has been modified in some way. The fundamental task of DKIM is to obstruct the widespread scam and spam email messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not get the message at all, or you’ll get it with a warning alert that most probably it’s not authentic. It depends on email service providers what exactly will happen with an email message which fails to pass the signature test. DKIM will also offer you an additional security layer when you communicate with your business partners, for instance, as they can see for themselves that all the e-mails that you send are authentic and haven’t been tampered with on their way.

DomainKeys Identified Mail in Shared Hosting

You will be able to get the most out of DomainKeys Identified Mail with each shared plans that we are offering without doing anything in particular, as the mandatory records for using this authentication system are created automatically by our web hosting platform when you add a domain to an existing web hosting account through the Hepsia Control Panel. If the particular domain name uses our NS records, a private cryptographic key will be created and kept on our email servers and a TXT resource record with a public key will be sent to the DNS database. If you send periodic messages to clients or business collaborators, they will always be delivered and no unauthorized person will be able to spoof your email address and make it seem like you have sent a certain message.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated hosting plans come with DomainKeys Identified Mail enabled by default, so in case you select a semi-dedicated hosting plan and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the authentication system will be created automatically – a private encryption key on our mail servers for the e-signature and a TXT resource record carrying the public key for the DNS database. As the protection is set up for a particular domain, all e-mail addresses created under it will have a signature, so you will not have to worry that the messages that you send out may not be delivered to their target address or that somebody may forge any of your email addresses and try to spam/scam people. This may be rather essential when you rely on e-communication in your business, since your colleagues and/or customers will be able to distinguish real messages from bogus ones.
