Postfix Cluebringer Policyd in Zimbra
Policyd is an anti-spam policy daemon for Postfix (written in C) that does Greylisting, Sender-(envelope, SASL or host / ip)-based throttling (on messages and/or volume per defined time unit), Recipient rate limiting, Spamtrap monitoring / blacklisting, HELO auto blacklisting and HELO randomization preventation.
It is included as a part of the Zimbra package, but it is not enabled by default.
Enabling policyd
First ensure sqlite is installed (It is listed as a suggested install).
To enable policyd, simply tell the Zimbra installation you want it enabled:
zmprov ms <mta server> +zimbraServiceEnabled cbpolicyd
After 1 to 2 minutes the zmconfigd process will detect that you want this service enabled, and automatically install the database and start the service.
