Setting Time Restrictions
Time restrictions are available in the spam filter and can be defined for individual rules to limit the effective period to only designated hours (indicated by the color red).
For example, to activate spam filtering only during business hours, select all time cells for Monday through Friday from 7:00 A.M. to 6:00 P.M. You will see a single red block in the middle of the schedule.
Conversely, if you only want to activate the spam filter during non working hours, select all time cells for Saturday and Sunday, and for the early morning and night hours as appropriate. You will see a single white block in the middle of the schedule (when the spam filter is not active) surrounded by a thick red border (indicating the times when the spam filter is active).
To set time restrictions,
1. Make the Anti-Spam/Set Policy page active.
2. Click Edit in the Time Restriction field.
3. Select time-cells using a mouse by clicking and dragging in a diagonal direction. Red time-cells indicate times when the rule will be in effect.
