One could make a reasonable case that a greylisting implementation that
keeps mail waiting long enough to generate soft bounces /is/ broken.

Aside from the fact that it seems to be introducing > 24hour delays in
your mail, a golden rule of anti-crap systems is that eliminating crap
from your inbox should not introduce it to someone else's; thus things
like challenge-response systems and blind sending of spam/virus bounces
to innocent addresses, are evil. Unless this is a one-off abberation
this seems like it's being over aggressive.
