Scope:
All Email Security Gateway, firmware versions 3.5 and above.
Answer:
In firmware versions 3.5 and above, the Email Security Gateway will store email until it reaches 75% capacity. After the mail/log storage reaches 75%, the Email Security Gateway will automatically remove emails from the message log to make room for new messages. The Barracuda Email Security Gateway will retain the meta information (to, from, subject, etc.) but it will not store the body of the email or any attachments once that email has been removed.
Note: Due to this process, the message log retention for customers will generally never be longer than 6 months.
