System Selector List (Signatures)

How to get here

Selectors allow a domain to have one DomainKeys selector and one DKIM selector enabled at one time. Multiple selectors are allowed in a domain to give the IMail Administrator capability to easily change from one public-key in DNS to another.

Important: Only one DomainKey selector and one DKIM selector can be enabled at one time for a domain. Example: A DKIM selector "selector1" is enabled for domain1.com. The IMail Administrator decides to enable "selector2" for domain1.com. "selector1" will automatically be disabled for domain1.com.

Important: After updating or creating a selector be sure to restart your SMTP and Queue Manager services.
