This is the position of an anti-spam policy in the list. The ordering of your 
anti-spam policies is important as the ZyWALL applies them in sequence. 
Once traffic matches an anti-spam policy, the ZyWALL applies that policy 
and does not check the traffic against any more policies.

from this zone and going to the To zone.

this zone from the From zone.

traffic using TCP port 25. POP3 applies to traffic using TCP port 110.
