[Spambayes] More Error Messages in log file?

It appears that all of the issues I am seeing are related to Spambayes not
seeing a message before my Outlook rules. This brings me to the sad
realization that SpamBayes is unusable in my environment.
I had asked a question about the purpose of the Filter timer and you
responded with "read the code". I don't have the code and I don't have the
time or inclination to read the code. If I did, I would write the code
instead. I don't know what language it is written in, I am guessing it is
not one that I am conversant in like assembly or VB. A simple answer would
have sufficed. Don't bother responding as it would make little difference
as I am already looking for a product that will work in my environment.
Hint: If you wrote the Outlook piece as a custom rule, I would have been
able to put it first to insure it would always fire before my rules moved
it. But I am sure you already thought of that.
You last comment about turning on background filtering is not the answer.
When turned on, almost all messages are missed (blank percent). This
setting seems to insure that it is always fired after the Outlook rules, at
least in OL2K.
It is too bad that Spambayes will not work for me in my environment as it
really looked promising. I did not want to use a proxy for one and I am not
willing to change the other software I am currently using.
Thanks for your time and input,

> 1). Does SpamBayes get control of the messages before any of my Rules?
This appears impossible to predict, varying by such things as system load,
processor speed, how fast email is coming in, Outlook version, and phase of
the moon. It's possible that Outlook will tell SpamBayes about a new
message before your rules or after your rules, it's possible that this will
change from message to message, and, if you have a rule that moves a msg
from one watched (by SpamBayes) folder to another watched folder, it's
possible that Outlook will tell SpamBayes about the message twice -- or not
The good news is that enabling "background filtering" (on the SpamBayes
Manager's Advanced tab) pretty reliably results in Outlook rules running
first. There's no known way to reliably get SpamBayes to run first.
If you are a VB coder, SpamBayes learns about new messages via ItemAdd
events on the watched folders. So the answer to all questions is "easy" at
that level: SpamBayes sees a new message when, and only when, Outlook fires
ItemAdd. Unfortunately, ItemAdd isn't reliable:
Outlook 2003 introduced a NewMailEx event which *may* be a reliable way (and
a more efficient way) to learn about new messages, but it looks like that
fires before rules (and, of course, isn't available before OL2003).

You really have to ask Microsoft, and they won't answer you <wink>: the
spam field is left blank if ItemAdd never told us about the new message, and
only MS can say exactly when Outlook fails to fire ItemAdd.

Read the code. You should use it if anything flaky is happening (like
messages not get scored).

A clues display scores the message from scratch. It doesn't matter to Show
Clues whether the message has been scored before, or, if the message was
scored before, what soore it got at that time. Show Clues always recomputes
everything from the current state of training.

"no percentage" means ItemAdd never told SpamBayes about the message.

Turn on background filtering. ItemAdd may still miss some messages, but far
