No, but he's going to do it anyway. The policy you want (unless you've got something personal against him) is to never see spam and backscatter, and to receive the valid mails that pass through his server. You can't have that if you blacklist him. You can't have that if you don't.
FWIW, I use blacklists via SpamAssassin, invoked from a Sendmail milter, so it's not a black and white decision that relies on a single such list. A degree of consensus is required.
It might be straightforward to cook up some SA rules that recognize mailman backscatter and drop it, at the risk of dropping legitimate bounce notices.
