Yep, in a more blunt-instrument way; we just try to use the last 6 months' mail for testing (roughly). I took a look at some old spam recently and it was amazing how different it was. Also, about 20-30% of all spam nowadays seems to be relayed through open proxies, so tactics have changed quite a lot. --j. ------------------------------------------------------- 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
