Does the fact that I'm getting this message mean that there is
wrong with my installation of courier-pythonfilter?
No, just ignore it for now. I'll fix it up soon.
And while you're at it, don't forget to change the name of
"whitelist-auth" to something without a hyphen. It appears like a minus
sign to python (at least in version 2.4.1), which causes the import
statement to barf (I'm not sure if you received my earlier message about
this ... I apologize if you have).
