Not complete documentation of MIMEDefang and spamassassin setup

Hook for reloading mimedefang when spamassassin rules have been updated \\
/etc/spamassassin/sa-update-hooks.d/reload-mimedefang
<code>
#!/bin/sh

if [ -x /etc/init.d/mimedefang ]; then
    /etc/init.d/mimedefang reread > /dev/null
fi
</code>

Add GPG key for sought rules
<code>
wget http://yerp.org/rules/GPG.KEY
sa-update --gpghomedir /var/lib/spamassassin/sa-update-keys --import /tmp/GPG.KEY
</code>
