I'm not receiving emails

Hello,

I use the contact form but I don’t receive emails. I used this documentation: http://kriesi.at/documentation/enfold/my-contact-form-is-not-sending-emails/
I use a @gmail.com email.

– No typo or spam
– WordPress is able to send emails
– Plugins are not the cause
– It works with Contact form 7

So what can I do? For aesthetics purpose I can’t use Contact Form 7.

Thanks
