Daily Magnitude and Monthly Magnitude for the IP address, Domain, 
and/or Network Owner 

Days since the first message was received from this sender

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 
(approximately 10 billion messages/day). Using the log scale, a one-point 
increase in magnitude equates to a 10x increase in actual volume. 

Monthly magnitude is calculated using the same approach as daily 
magnitude, except the percentages are calculated based on the volume of 
email sent over the last 30 days.
