How long does a message remain in the held queue before expiring?

The duration that a message remains in the held queue before expiring is essential for managing email security and preventing potential loss of important communications. Based on best practices and configurations commonly utilized in Secure Email Gateways, the correct answer reflects that messages will stay in the held queue for 14 days.

Holding messages for this period allows ample time for administrators or users to review and act on them, which is particularly important in identifying false positives in spam filtering or in managing potentially harmful content flagged by the system. After the 14 days, the message automatically expires and is removed from the held queue, ensuring that the storage system does not become overloaded with old messages that are no longer relevant.

This retention policy strikes a balance between maintaining necessary security protocols and allowing for an effective workflow, ensuring that the email environment is both secure and functional for users.
