I have an Exchange 2013 server at home but the receive connector cant seem to get any inbound emails. After diagnosing this issue with my DNS provider, it appears that the sender is unable to reach the exchange edge server on the above TCP ports to send inbound mail. I'm on Broadband 100 with dynamic DNS pointed to my Shaw router's external IP.
Is there any ACLs blocking inbound SMTP connections to my Shaw modem router? If so, why, and how do i unfilter my connection (all ports need to be opened).
