Request: Send a blank email to php-general+get-125952@lists.php.net to get a copy of this message
Hello all, I have searched the archives and cannot find an answer to this question. I would like to implement the same type of white list spam protection (where you must send a confirmation to be accepted) that php.net is using at my company. Does anyone know what type of software packages are used to protect the @php.net addresses? Thanks in advance, Gene
