I see no multiple settings for the same host/domain parameters here.
Postfix also needs to know that it is final destination for [184.108.40.206],
[220.127.116.11] and for all the corresponding domain names, otherwise mail
for those destinations will loop.
You need to list 18.104.22.168 and 22.214.171.124 in main.cf:proxy_interfaces
if those addresses don't already match main.cf:inet_interfaces,
and you need to list all the corresponding host/domain names in
mydestination, if those host/domain names aren't already listed in
