Creating a DKIM signing rule
A DKIM signing rule associates a private/public key pair with a set of domains and email addresses. Signing rule options let you determine which message headers to sign, how much of the message body to sign, and whether to attach additional signature tags for such items as signature date/time or expiration time. Signing rules are configured on the page .
The signing rules table includes the following information about each rule:
| Signing Rule Item | Description |
|---|---|
| Rule Name | Name of the signing rule. Click the rule name to open the Edit Signing Rule page. |
| Domain | Domain name to which the signing rule applies. |
| Selector | Name component in addition to the domain name used in the DNS query. A given domain may have multiple selectors (e.g., for location or organization division). |
| Signing Key Name | Name of the signing key associated with this rule. |
| DNS Text Record | Link that opens a Generate DNS Text Record dialog box. See Generating a DNS text record (public key). |
| Test Rule | Link to test whether the signing rule is valid. A successful test must be performed before a rule can be enabled. |
| Status | Indicator of signing rule status (i.e., enabled or disabled). A rule must be enabled in order to take effect. |
Configure the number of entries per page
From the pull-down menu Per page, select the number of signing rule entries per page, between 25 and 100.
