DomainKeys Identified Mail (DKIM) is an authentication system used to check that an e-mail message has been sent by an authorized person or server. A digital signature is attached to the email message’s header using a private key. When the message is received, a public key that’s available in the global Domain Name System is used to verify who exactly sent it and if the content has been modified in some way. The primary task of DomainKeys Identified Mail is to block the widespread scam and spam messages, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank, for example, but the signature does not correspond, you will either not get the email message at all, or you will get it with a warning alert that most probably it is not genuine. It depends on mail service providers what exactly will happen with an email message that fails the signature examination. DomainKeys Identified Mail will also provide you with an added security layer when you communicate with your business associates, for instance, as they can see that all the messages that you exchange are legitimate and have not been meddled with on their way.
DomainKeys Identified Mail in Shared Hosting
If you get one of the Linux shared hosting that we offer, the DomainKeys Identified Mail feature will be activated by default for any domain name that you register under your website hosting account, so you will not need to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our NS and MX resource records (so that the emails associated with this domain will be handled by our cloud web hosting platform), a private key will be created instantly on our mail servers and a TXT resource record with a public key will be sent to the DNS database. All addresses created using this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target audience and the recipients will know that the messages are authentic, since the DKIM option makes it impossible for unauthorized individuals to forge your e-mail addresses.
DomainKeys Identified Mail in Semi-dedicated Hosting
Our Linux semi-dedicated hosting come with DKIM activated by default, so in case you choose a semi-dedicated server package and you add a domain using our name servers through your Hepsia Control Panel, the records needed for the authentication system will be set up automatically – a private key on our email servers for the digital signature and a TXT resource record carrying the public key for the global DNS database. As the protection is set up for a given domain name, all email addresses created with it will carry a signature, so you will not need to worry that the emails that you send may not be delivered to their target email address or that somebody may spoof any of your email addresses and try to spam/scam people. This may be quite essential in case you use e-communication in your business, as your colleagues and/or customers will be able to distinguish legitimate emails from bogus ones.
