I use SES for transactional email quite often. Recently Amazon announced inbound email to SES and I'd like to receive a message and just have it forward to an SNS topic.
The setup is straight forward and I've followed the developer guide and everything seems to be set up correctly. I have an MX record for my subdomain I want this to work under and my domain is verified.
Except it doesn't work. If I try to send a message to my SES recipient. The MX record / domain is found but the mail bounces back to me with the error "530 Authentication Failure"
I've been searching google and the developer forums for hours now and I can't seem to find anyone else with this problem. I suspect there's something misconfigured but I don't see anywhere I can receive a better error message.
