2. How can I reduce or even dump the bounces all together so my queue's aren't filling up with junk bounces with invalid destinations?
Just don't use bouncing as a spam action at all if you filter after queue.. this is just a bad thing to do in general. Even if the destinations are 'valid' they are likely going to some poor shmuck who had his address forged. One thing you can always be sure of is that if a message is spam, the spammer is definitely never going to see the bounce.
I have a policy of outright blacklisting mailservers which send post-delivery bounces for spam filtering. I consider them nothing short of a malicious misconfiguration.
(pre-queue MTA rejections are OK, post-delivery bounces of invalid recipients are sub-optimal but a fact of life, sending a post-delivery spam notice is intentionaly attacking innocent bystanders.)
