Run an smtp check from mxtoolbox.com and paste the results into here.

The normal cause of this is due to low server disk space.  Check that the Server has more than 5GB of free space.

If disk space is low then Exchange will stop processing inbound emails and put them into a queue file until more space is available.

Check your router to see if it is still forwarding port 25 to your server correctly.

A port scan on that IP shows no open ports.  Restart the router / firewall and verify NAT settings

How are you doing the NAT on the Draytek?  Open ports or port redirection?

Personally I would take a backup of the Draytek, update the firmware and then reconfigure.

If you mail is working internally and you get an answer when telnetting on port 25 to the server then it does point to the router.

You could test port forwarding by opening a port to a client machine (something that isn't the server) and seeing if it works.  RDP to a client would be a good test.  If it fails then it points the finger at the Draytek still.

Check the servers event logs for errors with IIS and Exchange.  If there aren't any then I think a site visit to replace the router is in order.

Have you verified your domain Records and DNS settings on the server?   Verify that your public IP address is correct. Are your exchange certs self signed or 3rd party?   Verify your exchange certificates haven't expired.

The main DNS record and IP has remained the same? Was the router at fault?
