Outbound email is amongst the most likely thing to be blocked, so getting your "fix-me-feed-me" message outside the local network by some other means seems necessary. How far away does the message need to get? Conceptually, you need the sender and receiver of your message to rendezvous some how. The central server is a time-tested way of doing that. An alternative might be to let the customer run their own rendezvous service. Have your considered SMS messages?
