DomainKeys Identified Mail (DKIM) is an authentication system used to confirm that an e-mail has been sent by an authenticated individual or email server. A digital signature is added to the header of the message by using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to verify who actually sent it and if the content has been altered in some way. The prime task of DKIM is to stop the widespread scam and spam email messages, as it makes it impossible to forge 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 get the email at all, or you’ll get it with a warning notification that most probably it is not legitimate. It depends on email providers what exactly will happen with an email that fails to pass the signature test. DKIM will also give you an extra layer of security when you communicate with your business partners, for instance, since they can see that all the e-mails that you send are legitimate and have not been tampered with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

In case you host a domain name in a cloud hosting account with our company, all the compulsory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen the moment you add the domain in the Hosted Domains section of the Hepsia Control Panel, on the condition that your domain also uses our NS resource records. A private cryptographic key will be created on our mail servers, whereas a public key will be added to the global DNS database automatically by using the TXT record. Thus, you will not need to do anything manually and you’ll be able to make use of all the benefits of this email authentication system – your messages will reach any target audience without being discarded and nobody will be able to send out email messages forging your e-mail addresses. The latter is really important if the essence of your online presence suggests sending periodic newsletters or offers via email to prospective and existing clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our semi-dedicated servers come with DKIM activated by default, so if you pick this type of hosting and you add a domain name using our name servers via your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private cryptographic key on our email servers for the digital signature and a TXT resource record carrying the public key for the DNS system. Since the DKIM protection is set up for a specific domain, all email addresses created under it will have a signature, so you won’t have to worry that the emails that you send may not reach their target address or that someone may spoof any of your addresses and try to scam/spam people. This may be quite important if you use e-communication in your business, since your partners and/or customers will be able to distinguish legitimate email messages from phony ones.
