With which form you are having this issue? I did check all the three forms you have in your account but did not find that you have used "email@example.com" in any of the email alert.
Please be noted that if you want to receive submission emails to this "firstname.lastname@example.org", you should actually add it in the "Recipient Email" field of your email alert. The following guide should help you change the email address used to receive submission emails: http://www.jotform.com/help/41-Finding-out-E-mail-Address-used-for-submission-notifications
Hope this helps.
