Hi Dave,
I am no expert in Bayesian, but I would assume myself that the
emails you are considering including are not necessarily the same
spam emails that you actually receive and to some degree, you would
actually be polluting the DB.
I guess others will weigh in and confirm or deny my thoughts.

Subject: [Assp-user] Populating the SPAM DB
Hi Guys
This might be a crazy idea, and I haven’t thought through all the
consequences yet but I thought I’d put it out there anyway.
When building the Bayesian DB you ideally want a 1:1 ratio of spam/
ham, at least in my experience it’s fairly difficult to populate
the spam side of that to keep up with all the mail that’s getting
whitelisted and so my ratio is more like 0.6:1, the accuracy is
still very good so I’m not too concerned about it but I’d like to
get it closer to 1:1 if I can.
With that in mind, would it make sense to use relay attempts to do
this, perhaps mail to non-existant users too? Obviously you don’t
ever actually want to accept the final message of the attempt or
the various automated testing systems will flag your server as a
relay host, but would you be able to get enough of the message to
be useful in the Bayesian DB? Maybe accept right up to the final
piece of data and then reject it? Also you may be able to use the
PB data to mitigate this so you only ever go down this road if the
sending hosts is already at a certain score in the PB, which should
indicate that the mail itself is in fact spam since normal mail
servers shouldn’t get into the PB anyway.
Thoughts?
Dave
