Getting Bounce backs on Autoreply

Hi,

I love Jotform and it has been a great help. I do seem to be having a little trouble though. When someone enters and submits, I set up an AutoReply to thank them. I am now getting "mailer daemon" bounce backs after each and every auto reply. I was wondering if that may have something to do with Jotform since theres seems to be nothing wrong with my auto reply functions on any other emails.

Thanks

Michael
