Need little help configuring Email Gateway - Inbound

Hello everyone,

Thats my first steps with sophos central.

I'm trying to configure the Sophos Central Email Gateway.

I have verified my domain, added mailboxes.

Configure microsoft exchange - mail flow - Sophos started to "control" outbound mails.

But still missing something to start checking inbound mails.


Can anyone list the steps to make inbound mails work to ?
I am using microsoft exchange and domain in MX.
