I resolved this using a "Review Queued Mail" under 'File'.  I was unaware of this option, but when I used it, it sent me to the files that were being sent out over and over and over again.  From that list, I deleted the 3 emails, and problem is solved.  I found the answer in a post from 2007 about stuck queued mail. [:D]

I wrote an email to a business friend of mine asking for help on a graphic yesterday.  She emailed me today to let me know my email sent her over 500 copies of the same email.  I can see it sending, but how can I stop this?

Thanks for any help,
