Understanding the Email Reporting Pages
Each Sender Profile page contains the following data in the Current Information table at the bottom of
the page:
the page:
•
The global information from the SenderBase Reputation Service, including:
–
IP address, domain name, and/or network owner
–
Network owner category (network owner only)
–
CIDR range (IP addresses only)
–
Daily magnitude and monthly magnitude for the IP address, domain, and/or network owner
–
Days since the first message was received from this sender
–
Last sender group and whether DNS verified (IP address sender profile page only)
Daily magnitude is a measure of how many messages a domain has sent over the last 24 hours.
Similar to the Richter scale used to measure earthquakes, SenderBase magnitude is a measure of
message volume calculated using a log scale with a base of 10. The maximum theoretical value of
the scale is set to 10, which equates to 100% of the world's email message volume. Using the log
scale, a one-point increase in magnitude equates to a 10x increase in actual volume.

Sender Groups Report Page
The Sender Groups report page provides a summary of connections by sender group and mail flow
policy action, allowing you to review SMTP connection and mail flow policy trends. The Mail Flow by
Sender Group listing shows the percentage and number of connections for each sender group. The
Connections by Mail Flow Policy Action chart shows the percentage of connections for each mail flow
policy action. This page provides an overview of the effectiveness of your Host Access Table (HAT)
policies. For more information about the HAT, see the documentation or online help for your Email
Security appliance.
