Managing Quarantine Areas

InterScan™ Messaging Security Appliance (IMSA) can quarantine messages on the server in the $IMSA_HOME\queue\quarantine directory.

Trend Micro recommends quarantining messages that you think you might want to analyze and possibly send to the intended recipient later. Create different types of quarantine areas for different types of email, such as email that violates spam scanning conditions or email that violates message content conditions.

To manage quarantine areas:

You can get to a screen to modify quarantine areas from one of the following screens:

 

From the Actions screen of a policy rule:

If you are configuring the actions for a rule, do the following:

  1. Click Edit next to Quarantine to under Intercept actions. The Quarantines screen appears showing the available quarantine areas.

  2. To add a new quarantine area, click Add. To modify an existing quarantine area, click the area name and then click Edit. An edit screen appears.

  3. Next to Name, type the name of the quarantine area.

  4. To automatically delete quarantined email after a certain number of days, next to Delete messages older than, type the number of days from 1 to 60. This number represents the number of days after which IMSA deletes the quarantined messages. The value is exclusive. For example, if you type 15, IMSA deletes the quarantined messages on the 16th day.

  5. Click Save to return to the Quarantines screen.

  6. Click Done to continue selecting actions.

  7. To quarantine messages, select the radio button next to Quarantine to under Intercept and select the desired quarantine area from the drop down box.

 

From Mail Areas & Queues > Settings:

  1. Click Mail Areas & Queues > Settings. The Quarantine and Archive settings screen appears with the Quarantine tab displayed by default.

  2. Next to Disk quota per scanner service, do the following:

  1. Type the maximum size that you want the area to be.

    1. Select MB or GB.
       

When the total disk size for all the quarantined email messages exceed the quota on a scanner, the oldest quarantined messages are deleted first to keep the size under the quota.

 

  1. To add a new quarantine area, click Add. To modify an existing quarantine area, click the area name. An edit screen appears.

  2. Next to Name, type the name of the quarantine area.

  3. To automatically delete quarantined email after a certain number of days, next to Delete messages older than, type the number of days from 1 to 60. This number represents the number of days after which IMSA deletes the quarantined messages. The value is exclusive. For example, if you type 15, IMSA deletes the quarantined messages on the 16th day.

  4. Click Save to return to the Quarantine and Archive Settings screen.

  1. Click Save.
