1. People use a spamcop.net email address -- they receive their email at spamcop.net, from where it is forwarded. This ensures a good flow of spam and non-spam email through spamcop's servers. 2. People use spamcop's reporting service to identify spam. Spamcop then looks at the total number of emails received from an IP address and compares it to the number of complaints. So, actually, I was wrong in saying earlier that they use a ration of non/spam to spam, in fact, they use a ratio of total emails to spam emails. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
