DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email using a digital signature. When DomainKeys Identified Mail is activated for a given domain name, a public cryptographic key is published to the global DNS database and a private one is kept on the mail server. When a new message is sent, a signature is issued using the private key and when the email is received, that signature is checked by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily discern if the email message is legitimate or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been changed on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been added or deleted. This authentication system will boost your email security, since you can verify the legitimacy of the important emails that you get and your partners can do the exact same thing with the messages that you send them. Depending on the particular mail service provider’s adopted policy, a message that fails to pass the examination may be erased or may emerge in the recipient’s mailbox with a warning alert.
DomainKeys Identified Mail in Cloud Web Hosting
If you get one of the Linux cloud web hosting packages that we offer, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you add to your web hosting account, so you will not have to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain name will be handled by our cloud web hosting platform), a private 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 will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that they are legitimate, because the DomainKeys Identified Mail option makes it impossible for unauthorized parties to spoof your e-mail addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting packages come with DKIM enabled by default, so if you opt for a semi-dedicated server package and you add a domain using our name servers via your Hepsia Control Panel, the records needed for the validation system will be set up automatically – a private key on our mail servers for the electronic signature and a TXT record carrying the public key for the global DNS database. Since the protection is set up for a given domain name, all e-mail addresses created under it will carry a signature, so you won’t need to worry that the messages that you send may not reach their target email address or that someone may forge any of your email addresses and try to scam/spam people. This may be quite essential in case you use e-communication in your business, as your associates and/or clients will be able to distinguish legitimate emails from spoofed ones.
