Table 1: Configure Quarantine Malicious Messages
Action to take
Quarantine malicious messages (the default)—When you select to quarantine malicious email messages, in place of the original email, intended recipients receive a custom email you configure with information on the quarantining. Both the original email and the attachment are stored in the cloud in an encrypted format.
Note: When a quarantined email is released, it is allowed to pass through the SRX series with a header message that prevents it from being quarantined again, but the attachment is placed inside a password-protected zip file with a text file containing the password that the recipient must use to open the file.
