It is possible, but it will be strongly uncomfortable for you.

1. The bat! doesn't say to plugin, which final grade a letter has.

2. If plugin realizes auto-learning, it is necessary to know which final grade
the letter has.

3. To resolve this question, plugin just reads setting's file of The Bat!
and take the necessary value from it. Then it uses this value for auto-learning.
I.e., if the "bound" is 60, and plugin calculated the grade as 80, it means that
The Bat! will move this letter into "junk mail", or even delete it. And
vice-versa - if the grade is 40, plugin knows that this letter will come to
inbox folder. So, basing on this known "boundary" grade, plugin can
automatically "mark" and learn the letter as junk, or as not junk.

4. But this learning is still based only on plugin's own grade; it couldn't know
the final "collective" grade given to letter by all installed plugins and
calculated by The Bat! from all values and settings "minimum...
average...maximum". So, if you have the boundary at 60, and, for example, 2
plugins, and that the first give the grade 50, second - 70, it means that the
first will automatically "learn" the letter as not junk, but second - as junk.
So, the different plugin can auto-learn a letter as categorized differently. It
will be hidden error, which will cause one (or, both) of installed plugins to be
wrongly trained, so, the final result of filtering in process of this false
learning will come to 0% effect.

5. Resume: if you want to install more than 1 anti-spam plugins (at least based
on current API, published at Sep, 2002 and opened to everybody - the question of
Achim about "full access" to API was very strange - the API is opened since it
was published), you MUST always manually train them, i.e., mark ALL incoming
mail as spam/not spam.
