When I used to run an e-mail server all the time - I had installed a charting tool of some sort that read the spamassassin logs and would list various e-mails into buckets or categories - then it would display the hits from those categories using rrdtool. So you could look at your last 24 hours and see how much spam you got in the "Get Rich Now" category versus how many that day were in the Viagra category.
I have no idea what this thing was called - or where I found it (probably somebody's script on freshmeat) but it seemed pretty cool at the time. I also graphed the delivery time (not the time they put into the headers) based on when the e-mail arrived at the first postfix server. There is a clear 'bell curve' around noontime, with later in the day like midnight being a good time not to be receiving spam. The largest change in spam rate was between 8:30 and 9:30 in the morning (at the 'upslope' of the bell curve). I never really did understand why spam would do that, because you would think that spammers would be running processes all night long or whenever. I also wonder how much botnets of people's infected work computers (turned on at 8am) contributed to the problem. Or else, maybe spammers keep working hours too. :) Chris Thomas wrote: > I was just looking at my email because someone was suppose to send me > something.
