Given that the Amazon cloud is likely universally smtp blocked and will continue to be in the foreseeable future, you're probably not going to be able to work around this rejection problem by tweaking how postfix delivers mail. I blocked the Amazon cloud /18 in April, and sometime around late summer (US) a thread ran through the spam-l list causing universal blocking via the members. I'm sure the list of sites blocking it has only grown since then. Your best solution is to find a relayhost with good reputation from which you can send the email, one that doesn't cost you an arm and a leg to do so. Or, better yet, ditch the Amazon cloud and sign up with a decent colo/vps/web hosting shop whose IP space isn't universally smtp blocked. There are thousands of such providers out there offering ultra cheap service. Do some research and pick one whose IP space isn't in scorched earth territory. -- Stan
