That sounds a bit funny.

We have data on over 17 million IP addresses (collected using
http://mimedefang.org/reputation) Of those, about 9 million report at
least one ham or one spam -- the remainder either never made it past
greylisting or only tried emailing nonexistent recipient addresses.

Of those 9,102,875 hosts:

o 536,596 (5.8%) sent _only_ ham

o 7,821,574 (86%) sent _only_ spam

o The remaining 744,705 (8.2%) sent a mixture.  Most Yahoo! servers are in
  this category.

You saw less than 0.05% sending a mixture, which means you are probably
not getting a good sample.

Regards,

David.

statistically-useful amount of mail (>= 50K messages/day).

Sounds reasonable.  It's nice to see the numbers, thanks.

Yup.  I don't have enough data.  That's why I'm asking for more.
