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.
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
To configure basic scanning options
In the console on the primary navigation bar, click Scans.
In the sidebar under Views, select Scheduled Scans.
Do one of the following:
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.
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.
Check Only scan items modified since last scan to exclude the items that have not changed since the last scan.
Check Scan message bodies to scan message bodies.
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:
To select what to scan
In second panel of the schedule scan wizard, under Scan Location, to specify mailboxes to scan, select one of the following:
To specify public folders to scan, select one of the following:
To scan for content filtering rules
In the third panel of the scheduled scan wizard, click Enable content filtering to enable content filtering rule scanning for the scheduled scan.
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.
Click the box under the Enable column and select Enable to enable the rules that you want to apply to the scan.
To specify the scanning schedule
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).
Under Days to run on, check the days of the week that you want the scan to run.
Under Dates of the month to run on, select any of the following:
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.
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.
On the toolbar, click Deploy changes to apply your changes.
