Local quarantine

The Local quarantine uses your local file system to store quarantined emails and a SQLite database as an index. Stored quarantined email files, as well as database files, are encrypted for security reasons. These files are located under C:\ProgramData\ESET\ESET Mail Security\MailQuarantine (on Windows Server 2012).


If you want to have quarantined files stored on a different disk, other than the default C: drive, change the Data folder to your preferred path during installation of ESET Mail Security.

Local quarantine features:

SPAM and quarantined email messages will be stored in a local file system, not an Exchange mailbox database.

Encryption and compression of locally stored quarantined email files.

Mail Quarantine Web interface as an alternative to Mail quarantine manager.

Quarantine reports can be sent to a specified email address using a scheduled task.

Quarantined email files removed from the quarantine window (after 21 days by default), are stored in a file system (until automatic deletion occurs after a specified number of days).

Automatic deletion of old email files (after 3 days by default). For more information see File storage settings.

You can restore removed quarantined email files using eShell (assuming that they've not been deleted from the file system yet).

Inspect quarantined email messages and decide to delete or release any of them. To view and manage locally quarantined email messages, you can use Mail Quarantine manager from the main GUI or Mail Quarantine Web interface.


The disadvantage of using Local quarantine is, if you run ESET Mail Security multiple servers with Hub Transport Server role, you need to manage each server's Local quarantine separately. The more mail servers you have, the more quarantines you will need to manage.
