Procmail for M$Exchange (entry points requested)

Okay, I'm stuck using Exchange at my workplace.  I've spent a lot of time
looking into the WSS which has events for messages coming into Exchange.  The
only way to really do things is to allow everyone to write code and I guarantee
you that I don't trust that guy in the Accounting Department! :)

With that in mind I'm looking not at a port, per se, but for a way to reuse
different components of Procmail and make hook them into Exchange.  The entire
procmail system appears that it won't be able to be ported in it's current state:

So the two pieces I'm looking for in the code:

    1) where is the config file parsing?
    2) where are the matching rules for applied against an RFC822 message?

I think with these two components I should be able to get something started
which will get me what I need.  I'm mainly only interested in moving message
from one mailbox to another at this time, and perhaps some mail forwarding.  No
pipes or execs required, nor do I see adding that (for security reasons).


If you can point me to the code bits where I can find the above, I'll take a
crack at this.  Man I'm unhappy with the Exchange rules currently provided
server-side!  They are quite limited.

Thanks for any input you have!!
