DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an email has been sent by an authorized server or individual. An electronic signature is added to the header of the message by using a private encryption key. When the message is received, a public key that is available in the global DNS database is used to check who exactly sent it and whether the content has been altered in any way. The principal task of DKIM is to avert the widespread scam and spam messages, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not get the message at all, or you will get it with an alert that most probably it’s not genuine. It depends on mail service providers what exactly will happen with an email which fails to pass the signature test. DKIM will also supply you with an added layer of protection when you communicate with your business allies, for example, as they can see that all the e-mails that you send are genuine and haven’t been tampered with in the meantime.
DomainKeys Identified Mail in Website Hosting
The DomainKeys Identified Mail option is pre-enabled for all domains that are hosted in a website hosting account on our cloud platform, so you won’t need to do anything on your end to turn it on. The only requirement is that the particular domain should be hosted in a website hosting account on our end using our MX and NS resource records, so that the email messages will go through our mail servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the global DNS system automatically, so you won’t need to do anything manually on your end in order to activate this option. The DomainKeys Identified Mail validation system will allow you to send out credible e-mail messages, so if you’re sending offers or a newsletter to clients, for example, your emails will always reach their target audience, while unauthorized third parties won’t be able to forge 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 choose a semi-dedicated hosting plan and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the validation system will be created automatically – a private key on our mail servers for the electronic signature and a TXT resource record carrying the public key for the DNS system. As the DKIM protection is set up for a specific domain, all addresses created with it will have a signature, so you won’t have to worry that the email messages that you send out may not be delivered to their destination address or that somebody may spoof any of your email addresses and try to spam/scam people. This may be really essential when you use email communication in your business, since your associates and/or customers will be able to distinguish authentic emails from fake ones.
