The "Quarantine" policy takes a step further in email security over none/ignore by diverting suspicious emails to a separate folder, often labeled as spam or quarantine, instead of delivering them directly to recipients' inboxes. This policy provides an intermediate level of protection against potentially malicious emails while still allowing legitimate messages to be delivered. By implementing the "Quarantine" policy, domain owners can reduce the risk of users interacting with phishing attempts or malware-laden emails. However, it's crucial for organizations to regularly monitor the quarantine folder to ensure legitimate emails aren't inadvertently categorized as suspicious. Additionally, recipients should be educated on how to access and review quarantined emails, as some critical communications may end up there.
