This is quite possible. I have heard other stories of people using
things like greylisting and rbls to reject at smtp time that the only
things that eventually made it to SA were so limited that it would
produce odd results for bayes. From my experience, the more you throw
at bayes, the better it gets. The more selective you are, the less it
has to work with.

So are you saying for these purposes that you do not use RBLs or greylisting
or other similar tools that cut down on the obvious cycle consuming garbage?
Correct, i do not use RBLs or greylisting. However, I have 1 domain,
approx 100 users and receive only 2k messages/day. We have one machine
running qmail/SA/clamav which more than handles this load. I can afford
not to use rbls or greylisting - other larger setups may not be able to.
