The VirusWallServerSMTP variable configures the interface between your Screen and VirusWall:
(Optional) sys=Screen
prg=scan
name=VirusWallServerSMTP
values={ vwvalues }
(Optional) description="descriptive text"
enabled | disabled (the initial configuration is enabled)
Options for the vwvalues portion of the VirusWallServerSMTP variable are:
type=VirusWall
svc=viruswall-smtp
addr=vwserver (the default is the undefined address object, viruswall-server)
(Optional) holddown=downsecs (the default is 30*60 seconds)
(Optional) maxconns=#maxconns (maximum concurrent connections; the default is 3)
(Optional) minconns=#minconns(minimum spare connections; the default is 1)
Note that multiple addr items can be configured, allowing the use of secondary scanning servers. Each addr item can designate address common objects by name, or may give a naked (dotted-quad) IP address.
