ADX Email Alert

Hi, I found this ADX indicator on FF.com which sends an email on the ADX cross. However, it sends email after email and doesnt stop...Id like it to just send 1 email per cross...Can anyone edit the code so it doesnt flood the email box 10emails per second???

I think this would be a valuable indicator for our community since this is such a widely used TA tool.

Thanks,
