I have a flask app using flask-mail to send out emails, using the same mail setting, I can successfully send out emails locally from my MacBook Pro. But when I deploy the same code with same email setting on EC2 on Ubuntu14.04, I cannot send emails and got the following error:
send: 'ehlo flasks-app-server1.localdomain\r\n'
Exception in thread Thread-2:

I have googled this for about two hours and could not find a solution. Any help, please? Thanks!!
I figured it out. I AWS SES needs to verify the email for different region. I did not do that for the new region I am using.
