this would be a straight sample, before filtering, ip address blocking, etc. i realize this is difficult, as all of us go through much effort to reject this stuff as early as possible. but it will be a sample unbiased by your filtering techniques. How do you classify email as spam without adding bias?
reasonable question. i suspect you pull out the 0.5% of the inbound you actually wanted and consider the bias small. as the dnsbls alone block way over 90% of the inbound here, i would not classify that as small. randy
