    Default Spoofed Mail Not Being Spam Checked

    We've started to receive some targeted phishing messages, and most recently they have been spoofing email accounts that are "". This is causing these messages to NOT be spam checked. We are running Zimbra 8.0.2.

    I thought I configured amavisd to not spam check mail that was sent from the receiving MTA, but it seems that this is not the case. It looks like if the message contains a from address @ourdomain (spoofed or real), regarless of the sending MTA, it is not spam checked.

    How do I resolve this? Is there a way to have my cake and eat it too? Any help would be MUCH appreciated.
