Amedee> A couple of days ago I upgraded my server from Debian Lenny to Amedee> Debian Squeeze. Since then I'm seeing these lines in my Amedee> procmail.log: ...

This is my current version of Python: 1.1b1 is out: http://pypi.python.org/pypi/spambayes/ Is there a reason not to use that? Amedee> My questions are: Amedee> * is SpamBayes 1.1a6 compatible with Python 2.6.6? I run SpamBayes from my sandbox with the bleeding edge of Python 2.7. I have no doubt it will work with Python 2.6.x. Amedee> * if yes: what is my next course of action to make it work again? Convince the Debian folks to update their SpamBayes package perhaps? (Or update your installed package to what the Debian folks are distributing.) Amedee> * if no: how can I help? I have never written anything in Python Amedee> but how hard can it be? Not hard, but this doesn't look like a coding problem to me. It looks like a packaging problem. I suspect the Debian maintainers will be much more helpful than I can be. Skip
