Enable receiving and reply emails

I am working with @Abdelrahman_MoHamed on this - what we believe our core issue/blocker is we are trying to configure netcore to send reply email (inbound) email to discourse for processing.

What we cannot figure out is how to get that data (the inbound parsed email) into discourse for processing, where is the configuration screen we are looking at in netcore:

We believe we would want to enter a url similar to this:

https://forum.mamapedia.com/admin/email/handle_mail

We are confused however as when we look at the webhooks setup, it appears to be POST requests..

Also, we are making the assumption that we should be using webhooks to achieve our goal.
