    this can be achieved by 2 methods

    1. blacklisting the email into the spam system (checkout the Wiki for this solution)
    2. with header_checks within the postfix daemon (mattshaw.org » How to filter mail with postfix header_checks)

    Will this work with outgoing emails also?

    yes, if you pick up the choice with the header_checks. and those rules applies for both incoming and outgoing.
    have in mind that in the link that i gave you, the postfix's configs are placed in /etc/postfix/ but you should adjust the /opt/zimbra/postfix/conf/ files
