6.4.3 Top Spam Senders

Use this report to look at the top combinations of senders of spam messages and the first
SMTP server to which the sender sends spam. For example, if a sender sends spam through
two SMTP servers, there are two entries for the sender, one with each SMTP server.
Note: To look at anti-spam reports, each ZyXEL device must record anti-spam
messages in its log. See the User's Guide for each ZyXEL device for more
information. In most devices, go to Logs > Log Settings, and make sure Anti-
Spam is enabled.
Click Network Attack > AntiSpam > Top Senders to open this screen.

DESCRIPTION
This field displays the top combinations of senders of spam and the first SMTP
server to which spam is sent in the selected time interval, sorted by the number
of spam messages sent for each combination.
Each sender is identified by its e-mail address.
Each SMTP server is identified by its IP address. If DNS Reverse is enabled in
System > General Configuration, the table displays the domain name, if
identifiable, with the IP address (for example, "www.yahoo.com/200.100.20.10").
This field displays what color represents each sender in the graph.
This field displays how many spam messages each sender sent.
This field displays what percentage of all spam messages in the selected time
interval was sent by each sender.
This entry displays the totals for the senders above. If the number of senders in
the selected time interval is greater than the maximum number of records
displayed in this table, this total might be a little lower than the total in the main
report.
