starbuck7777 on "[Plugin: Contact Form 7] mail not send if your-email is strange anti-spam filter ?"

I made many tests with the default template
[contact-form-7 id="1234" title="Contact form 1"]
and the email send and works perfectly, except in those cases:

when i compile the contact form, if in the field [email* your-email] i insert strange email as "as@as.it" and i click on the button "send", the system send the email, appears the message "mail send" but I did not get anything

is it a anti-spam filter active ?
is possible remove it ?

Thank you very much !! :-)
