Perfect - that's exactly the sort of real-life based advice I was looking
for. Many thanks!

I run a small shared hosting environment, with a global bayes for all users
as not enough users are ready/willing/able to take the time to sort ham
(although more will press "this is spam") and in general, the results work
out well enough.

A portion of the bayes database is the header information from the
email. What does it mean for those headers that contain info specific
to a particular domain or site when it's transferred to another domain
or site where those specifics will be different?

see attached php/formail-script and list of ignored/stripped headers

we strip a large portion of headers including especially the Received headers with "formail" and preprend a egenric one on top from all samples before train them
Does that mean that transferring bayes databases between sites without stripping the headers wouldn't work - or it is just more effective if one strips the headers?
