Resolution

Mail Security provides a wizard that guides you through the process of configuring a scheduled scan.

After you configure the scheduled scan options, enable the scan so that it runs according to the schedule.

See Enabling a scheduled scan

You can configure the following scheduled scan options:

  • Name of the scan and the basic scan options

  • Mailboxes and the public folders that you want to scan

  • Content filtering rules that you want to apply to the scan

  • Scan schedule

To configure basic scanning options

  1. In the console on the primary navigation bar, click Scans.

  2. In the sidebar under Views, select Scheduled Scans.

  3. Do one of the following:

    Create a new scan

    In the sidebar under Tasks, click New scan.

    Modify an existing scan

    In the content area, under the Name column, double-click the scan that you want to modify.

  4. In the Scan name box, type the name for the scan.

    Mail Security lets you enter a maximum of 128 SBCS (single-byte character set) characters (64 double-byte character set characters) in the Scan name box.

    This option is available only when you create a new scheduled scan.

  5. Under Scan Options, check Stop after scanning ___ minutes to limit the amount of time for the scan, and then type the maximum scanning time in minutes.

    The default value is 120 minutes.

    If Mail Security reaches this limit, it stops scanning. The next scheduled scan starts where the previous scan stopped.

  6. Check Only scan items modified since last scan to exclude the items that have not changed since the last scan.

  7. Check Scan message bodies to scan message bodies.

  8. Under Choose messages to scan, select one of the following options:

    Scan all messages in the store.

    Scans all messages in the store.

    This is the default setting.

    Scan all messages from the past number of days.

    Scans all messages from the past number of days.

    Type the number of days in the box to the right.

    Scan all messages from the past number of hours.

    Scans all messages from the past number of hours.

    Type the number of hours.

    Scan all messages from the start date.

    If you select this option, do the following:

    • Click the drop-down arrow and specify the start date.

    • Select one of the following options:

      • To the date of the scan

        Performs the scan as of the start date that you specify to the current date

      • To the following date

        Performs the scan as of the start date that you specify to the date that you specify in the drop-down list

  9. Click Next.

To select what to scan

  1. In second panel of the schedule scan wizard, under Scan Location, to specify mailboxes to scan, select one of the following:

    All mailboxes

    Scans all mailboxes.

    This option is enabled by default.

    Exclude mailboxes

    Scans no mailboxes.

    Specific mailboxes

    Scans only the mailboxes that you specify in the list box.

    This option is available in the single-server view only.

  2. To specify public folders to scan, select one of the following:

    All public folders

    Scans all public folders.

    This option is enabled by default.

    Exclude public folders

    Scans no public folders.

    Specific public folders

    Scans only the public folders that you specify in the list box.

    This option is available in the single-server view only.

  3. Click Next.

To scan for content filtering rules

  1. In the third panel of the scheduled scan wizard, click Enable content filtering to enable content filtering rule scanning for the scheduled scan.

  2. Do any of the following:

    • To add a new content filtering rule, on the toolbar, click New rule.

    • To modify an existing content filtering rule, on the toolbar, click Edit rule.

    • To delete an existing content filtering rule, click Delete rule.

      See About creating a content filtering rule

  3. Click the box under the Enable column and select Enable to enable the rules that you want to apply to the scan.

  4. Click Next.

To specify the scanning schedule

  1. In the final panel of the scheduled scan wizard, in the Time of day to run box, select the time of day that you want Mail Security to perform the scan (in 24-hour format).

  2. Under Days to run on, check the days of the week that you want the scan to run.

  3. Under Dates of the month to run on, select any of the following:

    1st

    The scan runs on the first day of each month.

    15th

    The scan runs on the 15th day of each month.

    End of the month

    The scan runs on the 28th day of each month.

  4. Check Run scan at service start to perform a scan when the service starts.

    Do not enable the Run scan at service start option in a cluster environment.

  5. Check Run scan when virus definitions change to perform a scan when new definitions are received.

    Enabling Run Scan When Virus Definitions Change in conjunction with Rapid Release Definitions can significantly impact performance. Leave this feature disabled if you update definitions at frequent intervals. If this option is enabled, the scheduled scan runs each time definitions are updated. Because definitions are delivered frequently, the scan might not complete before new definitions are available. This can impact overall scanning performance.

  6. Click Finish.

  7. On the toolbar, click Deploy changes to apply your changes.
