Have you had a look at zmq support in amavisd?

$enable_db = 0;
$enable_zmq = 1;

Once you have that in place, you can run the newer amavisd-snmp-subagent-zmq
agent in combination with amavis-mc:

31801 ?        S      0:17 /usr/bin/perl -T /usr/sbin/amavis-mc -P /run/amavis/amavis-mc.pid
31803 ?        Sl     4:25  \_ /usr/bin/perl -T /usr/sbin/amavis-services msg-forwarder
31804 ?        Sl     4:34  \_ /usr/bin/perl -T /usr/sbin/amavis-services childproc-minder
31805 ?        Sl     3:37  \_ /usr/bin/perl -T /usr/sbin/amavis-services snmp-responder
 5653 ?        Sl     0:27 /usr/bin/perl -T /usr/sbin/amavisd-snmp-subagent-zmq -P /run/amavis/amavisd-snmp.pid
