Solve SPAM issues on zimbra mailserver

I have problems with spam on my Zimbra e-mail server. Zimbra uses postfix and spamassassin, I need someone with experience in dealing with spam to help me reduce the volume. We are getting spoofs from our own domain. For someone with experience in handling e-mail services this should not be so bad.
