Description of problem:

As described in SpamAssassin's man page, the program must create user_prefs in
$HOME/.spamassassin, where $HOME is the homedirectory of the user spamassassin
is run under.

When spamc is invoked from Postfix's master.cf file (as described at 
http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix) and SELinux is
enabled, Spamassassin can't create user_prefs file in /home/someuser, even if
"someuser" was created on purpose.


Version-Release number of selected component (if applicable):

spamassassin-3.0.4-2.fc4
selinux-policy-targeted-1.27.1-2.22
postfix-2.2.2-2
(stock Fedora Core 4 + updates March 06, 2006)

How reproducible:
Always.

Steps to Reproduce:
1. Invoke Spamassassin as a filter, from Postfix, as described in
http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix, with SELinux
enabled. Postfix users should be virtual users.
  
Actual results:
The process can't write user_prefs under /home/someuser.

Expected results:
A predefined system user should be created when installing Spamassassin (by the
rpm), with an appropiate, FHS-compliant homedirectory, in order to provide a
place to create user_prefs, when Postfix users are virtual users and SELinux is
enabled.

Spamassassin docs should indicate the correct way to proceed/configure in such
cases.
