public interface IMailRuleCondition

Remarks

The whole of what the rest of the system knows about the condition language. A compiled condition carries no expression, no parser state, and no authored text — the text is the operator's configuration and stays there, which is what keeps an address somebody typed into a condition out of every record that names the rule.

An implementation may throw. Totality is a classification the evaluator applies rather than a property of the evaluator underneath, so a condition that cannot be evaluated for the email in front of it raises the failure and MailRuleSetEvaluator turns it into a failed rule with a reason. What an implementation must never do is answer false because something went wrong.
