Email says from JotForm, even though I added my own SMTP?

Also, Email confirmations not being sent on submissions

I checked the form  Camp Registration Form in your account and the 2 email notifications are configured to be sent through your SMTP.

Please make an actual submission in your form to get it sent through your SMTP. Clicking the Test Email button in the notification will not use your configured SMTP, they are always sent through JotForm's mail server.

Pertaining to the other query, the mentioned form does not have autoresponder so submitters will not receive autoresponder emails if that's what you mean by "Email confirmations". You have to create an autoresponder if you haven't had one. Guide: Creating a Form Autoresponder, make sure the email field is set as the recipient.
