JotForm SMTP account error

I keep getting emails from JotForm that my sender emails are not configured properly (SMTP account error). However, I dont know which one of my emails is not configured correctly. Please help!

Also, when I look at the form ID, I see that it is effecting forms that have multiple email submissions using different sender emails. It has automatically changed all emails to be sent from noreply@jotform.com. Does this mean all the sender emails are configured incorrectly? Or does it just automatically change all sender emails associated with that form to noreply as a default?

Now to check which emails are not sent, you can follow this guide to see your form's email history: http://www.jotform.com/help/293-How-to-view-all-your-form-Email-History. From there, you can find what form ID is affected. You can then click on the icon to view more of its details

After clicking the arrow image, you will see more details of the email, like the status, subject line, form ID, etc...

Based from the details, you should be able to locate or find which form is affected.

You can edit your sender emails by following this guide: http://www.jotform.com/help/241-How-to-Edit-Delete-Sender-Emails-on-SMTP-Settings.

I hope that helps.
