This was designed to implement a graveyard service for mail > that can't be delivered via the preferred service. > > http://www.postfix.org/postconf.5.html#smtp_fallback_relay I tried this, but when a message to aws-email fails, it enters SOFTBOUNCE state and sits in the queue. What I'd like is for any failure on the default transport to fall back immediately to AuthSMTP.
