This is what the website says: "Subtle point: by default, address masquerading is applied only to message headers and to envelope sender addresses, but not to envelope recipients. This allows you to use address masquerading on a mail gateway machine, while still being able to forward mail from outside to users on individual machines."
So if i have masquerade_domains = example.com And I send from gg.example.com, the sender will get replaced to example.com so the `return-path` is also example.com. When the receiver replies to the message, how can gg.example.com receive it? Since it gets sent to example.com
