Since you already use Amavis::Custom, you can amend the new-hook:

> #  *custom hook: new() - may inspect info, may load policy banks

So, iterate $msginfo->per_recip_data, extract the domain from each 
recip_addr, extract the domain from $msginfo->sender and then make a 
decision which policy bank you wish to load via Amavis::load_policy_bank()
