An event’s eligibility for purging therefore depends on its age. For:
A captured event, that is, an email or web page captured by a CA DataMinder client or server agent, its age is calculated from the time the trigger activated.
Imported emails, the age is determined by the EMail.EventDateFromEMail parameter. This specifies whether the emails capture date is set from the date in the email itself or the date when it was imported. This parameter is described in the Platform Deployment Guide; search for ‘parameters: Event Import’.
Note: The default retention period can be overwritten by reviewers and policy administrators—see below.
