According to the source code of amavisd-new (amavis), to enable ZMQ support (including IPC and SNMP), we have to start the supporting service process (amavis-service) which is designed to start the ZMQ socket (via zmq_bind) and manage the message forwarding process.
But this port is not including these files (e.g. amavis-service, amavis-mc, etc.), so even we set enable_zmq=1 in amavisd.conf, amavisd still not using ZMQ.
I'd like to know is ZMQ support is designed to be not functional in this port (and why?), or this function should be work?
