Why is the email not being sent?

Question

WordPress

My site uses carparative mail from the hosting.timeweb.ru host. I created a simple form in contact fotm 7

<input name="тестовый">
<button>отправить</button>

when sending an error occurs
"An error occurred while sending the message. Please try again later."
I installed the plugin and made smtp send a test email, and it arrives

. But when I enter the same data (sender and recipient) here, an error occurs when sending. Hosting support told me

When sending a test email, an error does not occur, to solve the problem, we recommend contacting the support of the plugin used (contact form), or the developer of your site.

Unfortunately, hosting technical support does not analyze and fix user site code, so you will need to solve this problem yourself. You can find additional information on the thematic resources of the Internet or in the support service of the CMS you use.

If anyone else comes across this problem. Paste in functions.php
add_filter('wpcf7_spam', '__return_false');
