Thanks, Takayuki!
We created a small plugin which checks the user agent and that works pretty well.
<?php
// define the callback function, the arguments are optional
function dz1_skip_spam_ghost_check( $skip ) {
$user_agent = $_SERVER['HTTP_USER_AGENT'];
if (preg_match( "/xyz/i", $user_agent )) {
return true;
}
return $skip;
}
// hook the callback function to the 'example_action'
add_filter( 'wpcf7_skip_spam_check', 'dz1_skip_spam_ghost_check', 100, 1 );
?>
