I hadn't seen this before. Neat project.
Looks like he's created a new asyncore server which cooks up
and inserts request SMTPRequest objects in the ZServer request queue.

Well, in this case zope is already running.
I think you should use the existing publisher machinery.
Given an SMTPRequest instance foo, you should be able to
do foo.traverse(path, response) and get back an object.
This monster method is defined in ZPublisher/BaseRequest.py
