We are looking for a consultant to write an interface between SpamBayes and an e-mail client written in C. This interface should do filtering, which will consist of adding the X-Spambayes- Classification tag to the header of the mail body, and should do training. Ideally, you would make a COM with SpamBayes, having those interface functions for filtering (actually scanning) and training.

I hesitate in saying this, because I don't want to take work away from anyone, but there's not much to be done here, unless the COM server is a requirement. You can use either sb_bnfilter (the distribution includes a C version as well as a pure-Python one) with sb_bnserver.py or sb_xmlrpcserver.py to do this (using any C xmlrpc library, or manually crafting the xml and handling the socket connection). If Python won't be available, then a simple py2exe script can create binaries of these. If a COM server is a requirement, then there is work to be done, although it's basically all work on creating the COM server (under a dozen lines of Python - plus the existing SpamBayes package - can do all the rest). =Tony.Meyer
