AntiSpam options

Our Spam load has suddenly increased and the Boss is telling me to "do something!" .I obviously need to start tweaking our settings and I want to start with any options I might have within the Virtualmin context before I start to install options outside of it.

What can I do to tweak Spamassassin ?

Is there an easy way to enable Grey Listing?

If there is documentation on this site please point me towards that as I haven't yet been able to find it. We have a Virtualmin-Pro account on Centos5 and we use Postfix.

Thank You.
