No emails send to same domain

Hi,

For a client of me I created a website that contains 2 different contact forms. One is a contact us form, the other one is for reporting (sewer)problems.

But my client is not receiving any emails. The emails are send with noreply@vanterheijden.com (vanterheijden.com is the domain).

At first, when I was testing the emails, everything worked fine. The difference then was that the emails were sent to studio@degrafischewereld.nl (my business email). Now I’ve changed that to info@vanterheijden.com, the adress where the emails should be sent to, and now it stopped working.

I’ve tried several things but nothing seems to work. I’ve contacted the hosting provider and said maybe they know if in has something to do with spam filters or the PHP mail() function etc.

Does anyone know what the problem could be besides the hosting? This is not the first time it’s happening to me with CF7 and it’s getting me annoyed…

Thanks
