Enum MailRuleExecutionTrigger

Namespace

MailFathom.Application.Rules.History

Assembly

Which walk reached the email, which is the whole of an execution's identity beyond its rule.

public enum MailRuleExecutionTrigger

Fields

Arrival = 0

The email was reached by the arrival walk, which evaluates mail no pass has evaluated before.

RequestedRun = 1

The email was reached by a whole-mailbox run somebody asked for.

ScheduledRun = 2

The email was reached by a whole-mailbox run a rule's own declared schedule started.

Such a run walks the same mail a requested one does and reaches only the rules that declared the schedule trigger, which is why it is a walk of its own rather than a requested run with a different origin.

Remarks

The three are worth telling apart because they answer different questions. Mail is evaluated on arrival exactly once, so an execution recorded there is what a rule did to a message as it came in; an execution recorded for a requested run is what the rules concluded when somebody asked for the mailbox to be walked again, and the run it belongs to is named beside it. A scheduled walk is neither: nobody asked for it and no mail arrived, so recording one as either of the others would make the history answer a question the operator did not put.
