Email Settings working in test mode by not in contact form

I've entered the recommended email settings when configuring the Mail settings of the carts contact form.
When I test the settings in the admin console, I receive an email saying: This is a test email from your Maian Cart setup. Looks like your email is working just fine.

But when I try to send a message via the contact form, the email doesn't get received. I've checked the spam folder and it not there either.

Any suggestion?

Also can I send to multiple email recipients form the form?

Thanks.
