I just read the changelog, have you tried with $haproxy_target_enabled?

 From the release-notes:

- Supports receiving SMTP/LMTP connections through a HAProxy,
   recognizing 'PROXY protocol Version 1' data on the first line read,
   after a connection from HAProxy to amavisd has been established.
   Connection data (IP addresses and ports) received via this protocol
   end up replacing such data in the the Amavis::In::Connection object
   ($conn).  Set configuration variable $haproxy_target_enabled (also
   a member of policy banks) to true in order to enable this protocol.
