Email Pipes not working

Hi,

I am trying to setup email pipes in my contactform. I have gone through the documentation found at https://contactform7.com/selectable-recipient-with-pipes/

I have got 3 radio button and 1 checkbox. Code is

<label> Name <span style="float:right;">الإسم</span>
    [text* your-name akismet:author] </label>

<label>Telephone or E-mail Address <span style="float:right;">الهاتف أو البريد الألكتروني</span>
    [text* TelephoneorE-mailAddress akismet:author_email] </label>

<label> <span style="float:right; padding-top: 20px;">المبيعات</span></label>
[radio your-recipient default:0 "Sales|sales@xxx.org"]

<label> <span style="float:right; padding-top: 20px;">التسويق</span></label>
[radio your-recipient default:0 your-recipient "Marketing|marketing@xxx.org"]

<label> <span style="float:right; padding-top: 20px;">الشركات</span></label>
[radio your-recipient default:0 your-recipient "B2B|b2b@xxx.org"]

<label> <span style="padding-left: 20px;"> أرغب في تلقي الأخبار والمعلومات من غولدن غيت</span></label>
 [checkbox* your-recipient "I would like to receive news and information from Golden Gate|info@xxx.org"]

[submit "Send"]

In my wp-config I have defined define(‘WPCF7_USE_PIPE’, true); When i fill out the form I get an error message “There was an error trying to send your message. Please try again later.”

In the mail tab To: is set to [your-recipient]

Appreciate any help.
