That's what Full-Auto does right now ... if it understands the message, and it's temporary, it simply eats it without taking any action at all. It's a big performance hit if you let the error-causing addresses build up -- some addresses with "temporary" errors can stay that way for months, so unless you have some way to remove the addresses your server can end up doing little but processing bounces. One way to handle the situation is to set a short Renewal time on your list, so that sooner or later (sooner, that is) the failing address will also fail to confirm its subscription, and the problem there will end. However, that said, it sounds like there is a new, improved bounce processing algorithm in 1.8c.
