Yes, I have already read this. But I really need the recipient address and the sasl_username (to identify my user when I get the bounce) and, except if I'm wrong, I can't do this with postfix VERP.
For now, I'm looking at "MILTER" (on the advice of Wietse) or "SMTPD_PROXY" (which seems easier to implement for me).
Thanks, Msd
