DESCRIPTION

Click this button to clear the DNSBL statistics. This also clears the concurrent
mail session scanning bar's historical high.
The darker shaded part of the bar shows how much of the ZyWALL's 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.
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.
These are the DNSBLs the ZyWALL uses to check sender and relay IP
addresses in e-mails.
