It seems to work as advertised when I start it with:
/usr/local/sbin/postsrsd -u mailnull -p /var/run/postsrsd/postsrsd.pid
but when I use:
/usr/local/sbin/postsrsd -D -u mailnull -p /var/run/postsrsd/postsrsd.pid
postfix/cleanup complaints about an unreasonable packet length and the address is not rewritten:
