DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an email message has been sent by an authorized email server or person. An electronic signature is attached to the email’s header by using a private encryption key. When the message is received, a public key that’s available in the global DNS database is used to verify who actually sent it and whether its content has been changed in any way. The fundamental task of DKIM is to hinder the widely spread spam and scam emails, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not correspond, you will either not get the message at all, or you’ll get it with a notification that most probably it is not an authentic one. It depends on email providers what exactly will happen with an email which fails the signature check. DKIM will also provide you with an additional safety layer when you communicate with your business allies, for example, since they can see that all the emails that you send are genuine and have not been tampered with on their way.
DomainKeys Identified Mail in Cloud Hosting
The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a cloud hosting
account on our cloud platform, so you won’t need to do anything yourself to turn it on. The sole condition is that the particular domain should be hosted in a hosting account on our platform using our MX and NS resource records, so that the e-mails will go through our mail servers. The private encryption key will be created on the server and the TXT record, which includes the public key, will be published to the DNS system automatically, so you will not have to do anything manually on your end in order to enable this functionality. The DKIM authentication system will permit you to send trustable e-mails, so if you’re sending a newsletter or offers to clients, for instance, your email messages will always reach their target viewers, while unauthorized 3rd parties will not be able to spoof your email addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
Our semi-dedicated servers
come with DKIM enabled by default, so in case you select this type of hosting and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the validation system will be created automatically – a private cryptographic key on our email servers for the e-signature and a TXT resource record carrying the public key for the DNS system. Since the DKIM protection is set up for a particular domain name, all addresses created with it will carry a signature, so you will not need to worry that the email messages that you send out may not reach their destination email address or that somebody may forge any of your email addresses and try to spam/scam people. This may be quite important if you use electronic communication in your business, as your colleagues and/or clients will be able to distinguish genuine messages from fake ones.
