I could see that policyd is now in-built into MTA. I would like to know how to enable it. I saw a link: Tips Anti Spam : Aktivasi PolicyD & Rate-Limit Sending Message pada Zimbra Mail Server Versi 7 | Migrasi Windows Linux which has process to do the same. Any one in the community have successfully implemented policyd which is in-built with zimbra 7.0.1.
