dear Team i must check if PEAR::Mail with Net::SMTP is installed on my ispconfig System. how i can check this: As a dependency for direct_mail SMTP usage, you need PEAR::Mail with Net::SMTP support. Mail.php must be in the include path. Install it on your server, or if you only have a Webspace, put the necessary files into a /pear directory and add this directory to the include_path. Check whether it works using a modified example script. Don’t change the path in the include line because direct_mail will include Mail.php directly, too. thanks
