Not receiving emails since update

I don’t receive the e-mail contact anymore, I have contact form 7 working since 1 years (for a contact form and a request of newsletter), I tried with explorer and chrome and I’ve tested my email box.

I made the updates of wordpress (4.9.2) and contact form 7 yesterday.

No problem on my website, it says the e-mail has been sent.

For the moment I removed the contact form on my contact page as it’s not working but you can still see the newsletter on the homepage.

Thank you.
