Email I'm trying to send is not sent saying it's spam and put in my sent box.

Email I'm trying to send is not sent saying it's spam and put in my sent box. It is email that I compose using pictures I've taken that are in my files.  One of those files is from an email I send daily (and have for 15 years) to about 85 friends and family, and when it bounces and has placed in my sent file, and i try to send it again, I'm told that I'm over my limit for the day.  

This happened to me a few years ago and I had to write to the President of Cox to get some action, because Cox uses a service that had labeled me a spammer, and it was only when I wrote to him that they got it fixed.

An error occurred while sending mail.
