If they are indeed "old" addresses, surely you never send email from
those addresses any more? And thus you never need to accept bounces *to*
this addresses?
In fact, you don't really need to accept bounces to the *new* addresses
either. I don't accept bounces to dwmw2@???, for example,
because I never send MAIL FROM:<dwmw2@???>.
