This article will guide you on how to enable #DKIM on ISPConfig control panel. DKIM is an authentication standard for a domain name that sends an email, for use against spam and phishing.
It's possible to have more than one DKIM key published in your #DNS records. So, the DKIM selector is important for ensuring that your emails can be properly authenticated. The <selector> field specifies which DKIM key you're using, and the <header domain> field is filled with your domain name.
To generate DKIM Record in #ISPConfig:
1. Login to ISPConfig.
2. Click on Email.
3. Inside Email Accounts >> Select Domain and click on Mail Domain name.
4. Click on #DomainKeys Identified Mail (DKIM).
5. Tick Enable DKIM and Click on Generate DKIM Private-key Button.
6. Copy #DNS Record and add it to your DNS with its DKIM Selector.
7. Click on Save Button.
