SpamAssassin On CentOS Misconfigured

The problem I currently have is that all e-mails tagged by SpamAssassin as spam are deleted even though they are supposed to be moved to a different "probably-spam" file. In addition, I'd like to use the spamc + spamd configuration and I'm not using it now.

I tested that procmail is installed on my CentOS 5 server that's also using sendmail.

yum remove spamassassin // In case it is pre-installed. It was the last time I did this.

// Download it at spamassassin.apache.org:
wget [url]

tar xvfz Mail-SpamAssassin-3.2.3.tar.gz

cd /Mail-SpamAssassin-3.2.3

perl build/check_dependencies // Checks which perl module dependencies are missing that need to be installed before proceeding. Then install them

perl Makefile.PL

make

make install

Upload your own spamassassin/local.conf to /etc/mail/spamassassin

Code:
# This is the right place to customize your installation of SpamAssassin.

# See 'perldoc Mail::SpamAssassin::Conf' for details of what can be
# tweaked.

Upload.procmail to /home/tero // My e-mail user's name.

Code:

# Mails with a score of 13 or higher are almost certainly spam. Let's delete them.

/dev/null

# All mail tagged as spam (eg. with a score higher than the set threshold)
# is moved to "probably-spam".
:0:
* ^X-Spam-Status: Yes
/home/tero/mail/probably-spam

# Work around procmail bug: any output on stderr will cause the "F" in "From"
# to be dropped. This will re-add it.

}

I figured that this might be a permissions problem but what I can do without risking security?
