I've started using junkfilter, and it is working very well for me.

Now I want to "tune" it. So here are a few questions:

1. When junkfilter places a message in my junkmail file and I
don't want it to, how can I find out why it was marked as spam
(so that I can change it)? How can I find out which
pattern/rule caused it to be selected as spam? I need to be
able to identify which pattern to modify or remove.

2. When junkfilter does *not* place a message in my junkmail file
that I think it should, how how do I figure out why it did not?
For example, is there a way to determine why the email failed a
specific test? Are there techniques for putting debugging
messages into the procmai log file.

3. As an example, when I send myself an email, junkfilter
*always* sends it to the junkfile. How can I find the rule
that causes this so that I can change it so that I can do some
tests? Likewiise, when I subscribed to this group, the welcome
email was flagged as spam. I'd like to know why and which
pattern to look at.

4. Are there other debugging techniques that I should know and
could use? Are there some junkfilter variables that I can stick
into the headers of rejected messages? Setting VERBOSE=yes in my
.procmailrc file produces 200K per email. Is there a slightly more
brief setting?

5. Is there any documentation on junkfilter besides the README?

Thanks in advance for help.
