Depends what kind of bounce you mean
i.e quota full bounce
 can be avoided by postfix with vda patch
( which isnt official supported by postfix hackers )
but you cant use an additional lda then ( so you may loose filter stuff )
but in fact if you look in your logs daily
and have good Anitvirus and Antispam stuff integrated
and setuped
,backscatters by lda are very rare, and mostly have easy
solutions, like expand quota, deleting mailboxes etc
so its like others said avoid to bounce  to spam mails
is the most stuff, i.e clamav-milter helps a lot killing
worms etc on smtp income level, if sanesecurity is up again
this will work again for known spam
