Package: spamassassin Version: 3.1.7-2 Severity: normal

When using spamd child processes run as 'nobody' users who has no home dir. That causes a permission denied error in creation of bayesian filtering files, as explained here for instance:

http://lists.debian.org/debian-user/2007/01/msg03725.html

Adding something like:

--virtual-config-dir=/var/cache/spamassassin

to OPTIONS in /etc/default/spamassassin with nobody owning that dir would be appropriate. It would be better also creating a system spamd user with appropriate home and shell, instead of using nobody.
