Do you provide the full e-mail address of postmaster, or just the local-part
(to be qualified by the sender with an ounce of clue)? I can believe that
spammers automatically scan bounces for valid e-mail addresses, but not that
they'd read them manually, in which case just providing the local part (ie:
"please e-mail postmaster at this domain if this is a mistake") should have
the desired effect.

I'd avoid it if possible, but if you have to maybe think about putting a
higher threshold on for it?
