email validation failed on valid email

Hi, i’ve a problem.
with this very simple configuration:

<div align="center">
<label> Il tuo nome
    [text* your-name] </label>

<label> La tua email
    [email* your-email] </label>

<label> Il tuo telefono
    [tel* your-email] </label>

<label> Oggetto
    [text* your-subject] </label>

<label> Il tuo messaggio
    [textarea* your-message] </label>

<label> Accetti la normativa <a href="https://www.amicoasino.it/privacy-policy/">privacy</a> [acceptance acceptance-597] </label>

[submit "Invia"]
</div>

when is inserted an email, the validation fail

I’m using wordpress 5.8.2 and contactform7 v. 5.5.3.
What can i do to solve this?
Thanks
