domainkeys — enable or disable domainkeys signing
domainkeys = "enabled"
domainkeys = "disabled"
This directive is only valid if the Momentum dk_sign module is loaded. See “domainkeys – Yahoo! DomainKeys”
This directive instructs Momentum to enable (or disable) signing messages with a DomainKeys signature globally, on a specific domain, binding or domain within a binding. When the dk_sign module is loaded, signing occurs for all messages by default. This is the same as setting domainkeys = enabled at the global scope.
domainkeys is valid in the binding, domain and global scope.
domainkeys is also valid in the binding group scope.
