Postfix makes the safe assumption that sending the same input

Wrap it with a script that returns EX_TEMPFAIL (status 75)
when the buggy program dies with a signal.
#!/bin/sh
/some/where/buggy-program "$@"
status=$?
if [ $status -ge 128 ]
then exit 75
else exit $status
fi

Setting soft_bounce on the SMTP DAEMON has only effect on the SMTP DAEMON.
