You can do this with a setting in php.ini to say something similar to
sendmail_path = "/usr/sbin/sendmail -t -i -fdo-not-reply at york.ac.uk"

That simply overrides the default "sendmail" command used by the PHP 
mail() function.

The code to call the recaptcha module is all in 
/opt/zendto/www/{download.php,pickup.php,req.php,verify.php} and it's 
fairly obvious code when you take a look at it. It basically just does this:

       $reCaptchaPrivateKey = $theDropbox->recaptchaPrivateKey();
       if ($reCaptchaPrivateKey != 'disabled') {
         $resp = recaptcha_check_answer ($reCaptchaPrivateKey,
                                         $_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
       }

       if (($reCaptchaPrivateKey == 'disabled' || $resp->is_valid) .......

So you just need to replace that with the code to call any CAPTCHA of 
your choice. Put the PHP code for your choice of captcha module into 
recaptchalib.php.

Hopefully that's enough to get you going switching it to use something else.
