I manually generate a report daily to two addresses. Over the past few months, approximately once every ten days or so, it fails to send, Reason given is Message failed, check background software (anti-virus/firewall), etc.
I keep trying to re-transmit that days report several times, always with the same response, while on all other days it has gone smoothly at first attempt. So I am suspect of the anti-virus suggestion. Could there sometimes be a buried "bad character" that upsets the Reporter?
