You stated that the message pops up as soon as you leave from a WiFi Network. This means that your mail account is not connecting over cellular and thus you are getting an error message.
Open Settings ➔ Cellular - Scroll down till you see the name of the app that you use for emails and make sure that is set to ON.
This will allow that app to connect over a cellular data network as well when it is out of WiFi range.
