	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.
