Today I spent another few hours trying to dig out if I can find anything, finally it is fixed. The problem is the following line in the postfix’s configuration file /etc/postfix/main.cf, there is a line like below
mydestination = ericlin.me, ip-172-31-50-123.ec2.internal, localhost.ec2.internal, localhostThe problem is that I added my own domain (ericlin.me) to the list, which was wrong. After removing it, issue resolved!! ^_^. I hope this can help someone with similar problems.
