    One way is to add RBL lists.<br>
    <br>
    Modify your main.cf.template under smtpd_recipient_restrictions<br>
    <br>
                                   reject_rbl_client
    sbl-xbl.spamhaus.org,<br>
                                   reject_rbl_client bl.spamcop.net,<br>
                                   reject_rbl_client
    dul.dnsbl.sorbs.net,<br>
     <br>
    (untested with Kolab but I can't see why it should not work)<br>
    <br>
    A 2nd step would be greylisting. Postgrey works great. Not sure how
    you would make this work Kolab though.<br>
    <br>
    I run a separate postfix relay server so I'm not bound with trying
    to get this stuff to work with Kolab. I get almost no spam.<br>
