Error sending email message

Hello,

impossible to send email on the website http://www.standup47.com.

I called my hoster and wpmail() is activated.

I resolved the misconfiguration errors (from the new version) but it doesn’t work.

Here are my fields:

To: (my email… won’t write it here)
From: <info@standup47.com> (also tried whithout <>)
Subject: [your-subject] (I added the * in the form
Message: the different fields

What’s wrong ?

Thanks for your help
