As it turns out I set SMTPHOST to 127.0.0.2, and instead of
the usual smtp line in /etc/postfix/master.cf I've these 3 lines:


mypublicip:smtp   inet  n       -       -       -       -       smtpd
127.0.0.1:smtp      inet  n       -       -       -       -       smtpd
127.0.0.2:smtp      inet  n       -       -       -       -       smtpd  
-o
local_header_rewrite_clients=permit_tls_clientcerts -o  
relay_clientcerts=

The latter prevents address rewriting by requiring tls
authentication for rewriting and then preventing any
such authentication.

This is clunky.  Postfix is much happier when such
"bad" address rewriting is triggered by the client's
IP.
