DomainKeys Identified Mail (DKIM) is an authentication system used to check that an email message has been sent by an authorized server or individual. A digital signature is attached to the email’s header using a private key. When the email message is received, a public key that is available in the global Domain Name System is used to confirm who actually sent it and if the content has been edited in any way. The chief function of DKIM is to impede the widespread scam and spam email messages, as it makes it impossible to fake 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 email at all, or you will receive it with an alert that most likely it is not a legitimate one. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DKIM will also give you an added layer of protection when you communicate with your business partners, for example, as they can see that all the e-mail messages that you send are legitimate and haven’t been modified in the meantime.
DomainKeys Identified Mail in Shared Website Hosting
The DomainKeys Identified Mail option is pre-enabled for all domain names that are hosted in a shared website hosting account on our cloud website hosting platform, so you will not need to do anything yourself to enable it. The sole condition is that the particular domain name should be hosted in an account on our platform using our NS and MX resource records, so that the e-mail messages will go through our email servers. The private encryption key will be created on the server and the TXT record, which contains the public key, will be published to the global DNS database automatically, so you will not need to do anything manually on your end in order to activate this feature. The DKIM email validation system will allow you to send out trustable e-mail messages, so if you are sending offers or a newsletter to clients, for example, your email messages will always reach their target viewers, whereas unsolicited third parties won’t be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
If you pick any of the Linux semi-dedicated packages offered by us, you will be able to use the DomainKeys Identified Mail option with any domain that you register through your brand new account without any manual setup, as our high-tech cloud platform will create all the needed records automatically, on the condition that the domain name uses our name servers. The latter is required for a TXT record to be created for the domain, since this is how the public key can become available in the global DNS database. The private key will also be added automatically to our email servers, so anytime you send a new message, it will carry our platform’s electronic signature. The number of junk emails keeps increasing each year and quite often counterfeit addresses are used, but if you use our hosting services, you and your clients or colleagues won’t have to worry about that.
