Postman SMTP and Contact Form 7

I have Postman SMTP installed and configured correctly. I am receiving the test message. Contact Form 7 (v4.4.2) is still not working. It tells me the message was sent but I never receive it. I am using the same email address in the FROM field as I did in Postman. How do I know Contact Form 7 is using Postman SMTP settings to send mail?

This site is hosted on Bluehost. I have used Contact Form 7 on several other sites and have not had an issue (not hosted on Bluehost).

Thank you for your help!
