Using nginx to reverse proxy Discourse, I have followed half a dozen instructional posts, and the Discourse setup looks fine and everything works, and the logs show email sent with no errors indicated but they never get to Amazion SES. The setup is identical to my production system with the exception that I now want reverse proxy capability.
Is there any reason why nginx reverse proxy would stop emails, or in this case seemimgly make them disappear into thin air? [I know this sounds weird, but I do not know how to continue to debug these when there are no errors logged anywhere, only correct delivery messages.]
I am certain my Amazon SES is set up correctly as I use it for a lot of production systems.
