DomainKeys Identified Mail (DKIM) is an authentication system used to check that an email message has been sent by an authenticated person or mail server. A digital signature is added to the header of the email by using a private key. When the email is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and if its content has been edited in any way. The primary job of DKIM is to hamper the widespread spam and scam emails, 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 example, but the signature does not match, you will either not get the email at all, or you will receive it with a warning notification that most likely it’s not an authentic one. It depends on email service providers what exactly will happen with an email message which fails the signature test. DomainKeys Identified Mail will also give you an additional layer of safety when you communicate with your business partners, for instance, since they can see that all the emails that you exchange are legitimate and have not been modified on their way.
DomainKeys Identified Mail in Shared Hosting
If you obtain one of the shared hosting service that we’re offering, the DomainKeys Identified Mail option will be enabled by default for any domain that you register under your shard hosting account, so you won’t need to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private cryptographic key will be created immediately on our email servers and a TXT resource record with a public key will be sent to the DNS database. All email addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as periodic newsletters, they will reach their target audience and the recipients will know that they are authentic, as the DKIM option makes it impossible for unauthorized persons to forge your e-mail addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
When you pick one of the Linux semi-dedicated service offered by us, you will be able to use the DomainKeys Identified Mail feature with any domain that you register through your brand-new semi-dedicated server account without any manual intervention, as our high-tech cloud web hosting platform will set up all the mandatory records automatically, on the condition that the domain name uses our name servers. The latter is required for a TXT record to be set up for the domain, as this is how the public cryptographic key can become available in the global DNS system. The private key will also be added automatically to our email servers, so every time you send a new message, it will carry our platform’s electronic signature. The number of junk email messages keeps growing each year and very often bogus addresses are used, but if you make use of our web hosting services, you and your customers or partners won’t have to bother about that.
