I had been noticing that camera emails were mysteriously stopping between certain times and for the life of me I could not figure out why. I even switched from gmail to yahoo mail with the same result. I have since found out that both servers limit outgoing mail to 500 a day. It sounds a lot but if you have turned on motion detection (which is a total failure, by the way), you could get that much in a few hours. As it is I am missing most events of interest. Not sure what the solution is.
