Currently we cannot schedule for activation or deactivation of mail rules in Domino. So there is a feature request that, there should be a feature which will allow to activate or deactivate certain mail rules at chosen date and time. This will give flexibility to administrator to activate the rules at later time or deactivate when no longer required. So even if administrator is not present at that time, still server will do the scheduled rules execution as required.
e.g.- If any person is leaving the organization at specific date, an administrator can schedule a rule for that person which will be activated post his/her resignation.
