DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail has been sent by an authenticated mail server or person. A digital signature is attached to the header of the message using a private cryptographic key. When the email message is received, a public key that’s available in the global DNS database is used to confirm who actually sent it and whether the content has been modified in some way. The main function of DomainKeys Identified Mail is to hamper the widely spread scam and spam 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 or financial institution, for example, but the signature does not correspond, you will either not receive the message at all, or you’ll receive it with a warning note that most likely it’s not an authentic one. It depends on mail service providers what exactly will happen with an email message which fails the signature check. DomainKeys Identified Mail will also provide you with an added layer of protection when you communicate with your business associates, for instance, since they can see that all the e-mail messages that you exchange are legitimate and haven’t been manipulated in the meantime.
DomainKeys Identified Mail in Semi-dedicated Hosting
When you select one of the Linux semi-dedicated services offered by our company, you will be able to use the DKIM feature with any domain that you add to your brand-new semi-dedicated account without any manual setup, as our high-tech cloud web hosting platform will create all the compulsory records automatically, on the condition that the domain uses our name servers. The aforementioned is required for a TXT resource record to be set up for the domain, as this is how the public encryption key can become available in the global DNS database. The private key will also be added automatically to our email servers, so every time you send out a new message, it will have our platform’s digital signature. The number of junk emails continues to rise each year and very frequently spoofed addresses are used, but when you use our hosting services, you and your customers or partners won’t need to worry about that.
