Keep a copy of clean messages
By default, Forcepoint Email Security Cloud does not keep a copy of any messages unless they are quarantined, in which case they are held for 30 days before being automatically deleted. Checking Keep a copy of clean messages allows Forcepoint Email Security Cloud to keep a private copy of clean email messages, for a short period, separate from the quarantine area, to aid in the process of spam tuning when the “Report this email as Spam” link is used (see Report this email as spam for more details). If Forcepoint Email Security Cloud has the original message available, our operations staff and future automated systems can analyze it.
