Do I need to set up DKIM for my cloudresolve.net email accounts? No. When using cloudresolve.net name servers and mail servers, DKIM is automatically activated on your domain, which means you don't need to do anything. All emails you send from your domain will automatically be sent with a digital, encrypted signature. To protect you against spoofing and phishing attacks, our mail servers also always check all emails that are sent to you for the digital DKIM signature. ________________________________________ What is DKIM and what does it do? DomainKeys Identified Mail (DKIM) is an email authentication method. When DKIM is enabled it adds a digital signature to every email that is sent. This signature is invisible to the sender and recipient but can be identified by mail servers. The mail servers can check for the digital signature to verify that the email address is indeed connected to the domain that it claims it is and that it is allowed to send emails from that domain. ________________________________________ Why do I need DKIM? DKIM helps you in two ways - when you're sending emails and when you're receiving emails. When you send an email DKIM adds an invisible signature that can be used by the receiver's email provider to validate your email. This means that your email is less likely to be accidentally flagged as spam. It also means that you can protect your domain against malicious emails that claim to be sent on your behalf. When you receive emails the mail servers automatically check if the email that is sent to you is using a digital signature to verify itself. If not, the emails will in most cases be flagged as spam. This is one way to protect you against spam emails, spoofing and phishing attacks. ________________________________________ How can I add DKIM if I'm not using cloudresolve.net name servers? If you're not using cloudresolve.net name servers but are using our mail servers, you can still add DKIM to your domain. You need to add some specific CNAME records for this.
