I had a similar problem once upon a time. I had a form, whose results
were getting emailed, sending duplicate submissions occasionally.

The cause, I surmised, was that someone was stopping the download of the
page before it finished, so the code execution stopped, or they were
double clicking the submit button.

The cause was a bit hazy, though ignore_user_abort() fixed it for me. Is
it possible, in your case, that the code is partially executing, and
giving you the impression it's sending dublicate mails?
