Messages aren't received

I have a gravity form set up on my WordPress site and I'm trying to send to two different email accounts with no luck. I've installed the WP-Mail-SMTP plugin.

The first account is a GoDaddy account. It receives the test messages that I send through the WP-Mail-SMTP plugin, but will not receive any submissions through the forms.

The second account is an AOL account and doesn't receive any message; not from the test nor the notification.

I know things are working because I have bcc'd myself on the forms (using a gmail account) and I receive the messages just fine.

Any suggestions on how to fix this?

Thanks for the suggestions. I just checked for theme conflicts and I'm waiting to hear back if that solved the issue, if not, I'll try resolving plugin conflicts. I only have one other plugin installed so that shouldn't be a problem.

The email addresses are separated by a comma.

Ah, so you are good to go I take it?
