Is this like before, when you were getting a 504 error? Could you post a screenshot of what you see when trying to access email?
server IP address could not be found.
Try:
Clear the DNS. Follow the procedure below to the letter.
1. Turn off all of the devices using the modem (all phones, iPads, computers, etc.)
2. Unplug the modem's power from the wall socket.
3. Wait a minute, then plug the modem back in.
4. Wait about 5 minutes after all the lights on the modem are back on, then turn all your devices on one-by-one.
have followed your instructions, still no email, all other sites ok

Remy
