I submitted an Alexa Skill for being tested by Amazon's Alexa Team. My skill sends an email with the results of the interaction.
Email is sent and received by email@example.com (the first email address used for the first level of test) and also when I test with my gmail address email.
The second level of tests appears to be done with the Amazon tester's email address, with the structure firstname.lastname@example.org where tester is the identification of the tester.
The skill is rejected because the tester doesn't receive the email and effectively I can see that email that should be sent are appearing Hard Bounced in my email's providers (mandrill).
I feel that the email is blocked by a kind of security wall on Amazon side. What can be done to overcome this issue and progress on the approval process for my skill?
