A legitimate message may occasionally be classified incorrectly. Quarantine keeps the message away from the user while allowing later review.<\/p>\n<h2>What kinds of messages may be quarantined?<\/h2>\n<ul>\n<li>Messages with a high spam score<\/li>\n<li>Email containing suspicious links<\/li>\n<li>Messages with detected malicious attachments<\/li>\n<li>Email with serious authentication concerns<\/li>\n<\/ul>\n<h2>How long should quarantine retain messages?<\/h2>\n<p>Retention depends on organizational policy and operational needs. Keeping messages indefinitely is generally unnecessary.<\/p>\n<h2>Can users release messages?<\/h2>\n<p>Some environments allow users or administrators to review and release quarantined messages.
