[Spambayes] spambayes and maildrop (xfilter)

[b52 at entrap.de]

Hi guys,

maybe someone can help me with this one. I configured postfix to transport
every mail with maildrop and included a maildrop rule to pipe incomming
mails to sb_filter.py
If this happens I get the following error in mail.log:

Apr 24 03:08:20 hades postfix/pipe[29142]: 6F04D27CA: to=<b52 at entrap.de>,

Well to tell you the truth I don't understand that message at all. Maybe
some python geeks do..
My maildrop rule is:

xfilter "/usr/bin/sb_filter.py -d /home/vmail/bayes.db"

I tried xfilter with another binary and it works fine.
Thanks for any help
bye, b52
