By 'collateral mail' I think you mean 'autoresponses, including bounces
and vacation messages'. In which case it _should _always_ generate a
DSN.

You should never blackhole. Reject it up-front at SMTP time should you
so desire, but if you accept it then you have a responsibility to either
deliver or bounce it.

Actually it's relatively easy for Joe to filter out bogus DSNs and avoid
the 'collateral spam'. That's that BATV does for him.
