Mark, afaik if the 'From ' (not 'From:') or 'Return-Path:' headers are
set correctly, the bounce will go to the original sender. Double-
bounces will go to the address specified in sendmail's config file
'DoubleBounceAddress' (default = postmaster), which is usually correct
for a double-bounce message.

For those on the list not familiar with the terminology, a double-
bounce is one where the bounce address failed. For example,
joe@yourserver send a message to someone@yahoo. If 'someone' doesn't
exist at yahoo, yahoo will generate a bounce message to joe@yourserver
indicating such (assuming that joe@yourserver is set in the
'Return-Path:' of the original message).

If joe@yourserver can't accept the bounce from yahoo (e.g.,
joe@yourserver is over quota or misconfigured), that generates a
double-bounce message, which should go to root or postmaster (or some
other address guaranteed to be working).
