This how you get rid of email from Nobody. Change the wp_mail part of the code (near the bottom of the page in the functions.php file which is located in the wp-includes folder to this below:
function wp_mail($to, $subject, $message, $headers = ”) {
if( $headers == ” ) {
$headers = “From: ” . get_settings(‘admin_email’) . “\n”;
“Content-Type: text/plain; charset=\”” . get_settings(‘blog_charset’) . “\”\n”;
}
return @mail($to, $subject, $message, $headers);
