DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail message has been sent by an authorized email server or person. A digital signature is added to the header of the message by using a private cryptographic key. When the message is received, a public key that’s available in the global DNS database is used to check who actually sent it and if its content has been altered in any way. The fundamental job of DKIM is to avert the widespread scam and spam emails, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t match, you will either not get the email at all, or you will receive it with a warning that most likely it is not legitimate. It depends on mail service providers what exactly will happen with an email which fails the signature test. DKIM will also offer you an extra layer of protection when you communicate with your business allies, for instance, as they can see for themselves that all the emails that you exchange are genuine and haven’t been modified in the meantime.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers come with DKIM enabled by default, so if you pick a semi-dedicated server plan 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 mail servers for the electronic signature and a TXT record carrying the public key for the DNS database. As the protection is set up for a particular domain, all email addresses created using it will have a signature, so you will not have to worry that the emails that you send may not be delivered to their destination address or that somebody may fake any of your addresses and attempt to scam/spam people. This may be quite important when you use electronic communication in your business, as your associates and/or clients will be able to distinguish authentic emails from fake ones.
