Jeff G. Posted August 4, 2005 Share Posted August 4, 2005 Sorry, that doesn't hold water. They don't change the Richter and Fujita scales as functions of world seismic activity, global warming, or the Santa Ana tradewinds, why should SenderBase Magnitude change? I see that Mike Easter posted the first paragraph of what you quoted in http://news.spamcop.net/pipermail/spamcop-...ber/063131.html, but didn't reveal his source. What was your source? Thanks! My calculations from SenderBase's webpage are about 34% higher. Link to comment Share on other sites More sharing options...
Jeff G. Posted August 4, 2005 Share Posted August 4, 2005 I see some of that info presented on SenderBase's Magnitude Help Page. On that basis, a Magnitude of 2.3 would be about 178-224 emails/day, whereas a Magnitude of 2.2 would be about 141-178 emails/day. That still doesn't explain how 2.3 could be 33% less than 2.2. Now, the thick plotens - here are the current stats from http://www.senderbase.org/?searchBy=ipaddr...g=209.53.184.21: ...................| Magnitude | Vol Change vs. Average | EstVol/Day* Last day ......|...... 0.0 .....|.............. -100% ............|......... 1 Last 30 days |...... 3.1 .....|................ 695% ............|.....1.3K Average ......|...... 2.2 .....|.....................................| ...0.16K * based on SenderBase's Magnitude Help Page (25% lower than my previous estimates based on the table on http://www.senderbase.org/) I have just come to the conclusion, based on a detailed analysis of the numbers on http://www.senderbase.org/, that either the "Estimated Daily Volume (m)" on that page is inflated by 49.6 to 51.3 percent, or the actual estimate of world Daily Volume is between 14.96 and 15.13 billion emails, rather than 10 billion emails. As far as "Monthly Magn." (which I now take to mean "log10 of the estimate of the Monthly Volume PER MONTH NOT PER DAY"), those figures are consistenly one full Magnitude below what they should be, indicating an estimated average Month of only three days.

Lollercoaster Posted August 4, 2005 Author Share Posted August 4, 2005 Interesting stuff. That doesn't seem correct at all. Link to comment Share on other sites More sharing options...

My calculations from SenderBase's webpage are about 34% higher. 31276[/snapback] Source was http://www.senderbase.org/?page=help Remember their scale is a factor of the total amount of mail sent. For the magnitude to remain constant, the total volume of mail would have to remain constant. Magnitude is not a equation of the exact amount (number of pieces) of mail sent, (though it does relate), it is a measure of the percent of mail sent by one specific IP address or domain as compared to the total amount of mail sent by all servers calculated using a log scale with a base of 10.
