I had outbound problems, some very similar to yours
If all else fails, you don't have to actually be a spammer (and I'm not) but “SendGrid” will punch your ticket for free if you send less than 400 emails a day.
They seem able to send anything to anybody with access to the disposition of the email if you should need it.
Looking at inbound headers too, I notice a couple of well known reputable companies using SendGrid.
