LABEL	DESCRIPTION
Refresh	Click this button to update the information displayed on this screen.
Flush	Click this button to clear the DNSBL statistics. This also clears the
	concurrent mail session scanning bar’s historical high.
Concurrent Mail	The darker shaded part of the bar shows how much of the ZyWALL’s
Session Scanning	total spam checking capability is currently being used.
	The lighter shaded part of the bar and the pop-up show the historical
	high.
	The first number to the right of the bar is how many e-mail sessions
	the ZyWALL is presently checking for spam. The second number is the
	maximum number of e-mail sessions that the ZyWALL can check at
	once. An e-mail session is when an e-mail client and e-mail server (or
	two e-mail servers) connect through the ZyWALL.
DNSBL Statistics	These are the statistics for the DNSBL the ZyWALL uses. These
	statistics are for when the ZyWALL actually queries the DNSBL
	servers. Matches for DNSBL responses stored in the cache do not
	affect these statistics.
#	This is the entry’s index number in the list.
DNSBL Domain	These are the DNSBLs the ZyWALL uses to check sender and relay IP
	addresses in e-mails.
Total Queries	This is the total number of DNS queries the ZyWALL has sent to this
	DNSBL.
Avg. Response	This is the average for how long it takes to receive a reply from this
Time (sec)	DNSBL.
No Response	This is how many DNS queries the ZyWALL sent to this DNSBL without
	receiving a reply.
