I'm not developing a qmail SRS implementation, but I do use qmail, so
perhaps I can try to shed some light on this.  From what I understand of
SRS, I would think that it would be handled somewhere around
qmail-queue, not qmail-local.  

qmail-queue has no idea if the message is remote or not; it is
qmail-send which decides if the message is remote or local.  I guess
making the secret file readable to the qmails user only (qmail-send is
run as qmails), one could modify qmail-send to do srs.  In fact, it
seems the only way to handle srs would be by qmail-send, since
qmail-send prepends every message to a virtualdomain by a
string---destroying srs bounces that are supposed to start with the
string SRS.
