DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email message by using an e-signature. When DKIM is activated for a specific domain name, a public encryption key is published to the global DNS database and a private one is kept on the mail server. If a new message is sent, a signature is generated using the private key and when the email message is received, that signature is authenticated by the POP3/IMAP server using the public key. Thus, the recipient can easily recognize if the message is legitimate or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been changed on its way as well, so DKIM can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or removed. This email authentication system will increase your email safety, as you can verify the authenticity of the important email messages that you get and your colleagues can do likewise with the email messages that you send them. Based on the particular mail service provider’s adopted policies, a message that fails the check may be erased or may be delivered to the recipient’s mailbox with a warning flag.
DomainKeys Identified Mail in Cloud Hosting
If you obtain one of the Linux cloud plans that we are offering, the DomainKeys Identified Mail functionality will be enabled as standard for any domain name that you add to your shard hosting account, so you won’t have to set up any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain name will be handled by our cloud web hosting platform), a private encryption key will be issued right away on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses created using this domain name will be protected by DKIM, so if you send email messages such as regular newsletters, they will reach their target audience and the receivers will be sure that they are genuine, because the DomainKeys Identified Mail option makes it impossible for unauthorized persons to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our Linux semi-dedicated servers come with DKIM activated by default, so in case you select a semi-dedicated plan and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email validation system will be set up automatically – a private encryption key on our email servers for the digital signature and a TXT resource record carrying the public key for the global Domain Name System. Since the protection is set up for a particular domain name, all e-mail addresses created with it will have a signature, so you will not need to worry that the email messages that you send out may not reach their target email address or that somebody may forge any of your email addresses and try to spam/scam people. This may be quite essential when you use email communication in your business, since your colleagues and/or customers will be able to distinguish authentic emails from false ones.
