DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an email has been sent by an authorized person or email server. A digital signature is added to the header of the email using a private encryption key. When the email message is received, a public key that is available in the global Domain Name System is used to confirm who exactly sent it and whether the content has been edited in any way. The principal task of DomainKeys Identified Mail is to hamper the widely spread spam and scam email messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t match, you will either not get the email at all, or you will get it with a warning notification that most probably it is not genuine. It depends on email providers what exactly will happen with an email message which fails to pass the signature test. DomainKeys Identified Mail will also give you an added layer of security when you communicate with your business associates, for instance, since they can see for themselves that all the emails that you exchange are genuine and have not been meddled with in the meantime.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated hosting service come with DomainKeys Identified Mail enabled by default, so in case you opt for a semi-dedicated server plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private key on our mail servers for the digital signature and a TXT record carrying the public key for the DNS database. As the protection is set up for a given domain, all email addresses created with it will have a signature, so you won’t need to worry that the email messages that you send out may not reach their destination email address or that somebody may spoof any of your email addresses and try to scam/spam people. This may be extremely important in case you use e-communication in your business, as your partners and/or customers will be able to distinguish real messages from spoofed ones.
