Hi Cindy and Gordon,
Thank you for the info! We ran into this exact issue when we first starting using Gravity Forms and as a result switched the from email to be a gmail account, very frustrating indeed!
Since writing the original information someone took a screen shot of their issue and it was with reCAPTCHA. I removed the reCAPTCHA button from the form which has seemed to help. Now we just have some notifications that are not being automatically forwarded after forms are submitted. If anyone has any suggestions for this let me know!
