Indeed as Era wrote, it's impossible to pick the bounced address from
message reliably. I use pm-jadaemon.rc which detects the daemon messages
(not necessarily bounces, but "undeliverable" and so on...), and it's
nightmare to get every MTA detection there.
Sometimes I wish they would all use sensmail which have a standard
error message format.
