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.

I can take care of this for you. Depending on the version of Postfix (2.8+) there is a feature called postscreen that will cut out most of the spam. After that filtering with Amavisd, Spamassassin, and a few other filters will cut out most of what remains. Adding SPF, DKIM and DMARC records will stop you getting spoofed emails. If your version of Postfix is older than that I can compile the latest version for you without breaking the rest of Zimbra.
