I read the WGET topic and do not understand how this can help me.
The bounce.cgi (Perl) script takes the message and actually passes it through another program to a PHP script through the web server, using the system utility wget, by default. This was done due to prevent the need for a separate MySQL database config file for .cgi files and because many servers do not allow forwarding to PHP scripts.
Some servers do not have the default "wget" utility available, so an alternative must be configured manually in bounce.cgi.
# Program and paramaters to pass URL to
# Usually works as default (may be /usr/local/bin/wget or other)
$http_program = "/usr/bin/wget -O /dev/null " . $listmail_url . "/bounce.php";
This could be changed to use the "curl" alternative, for example:
$http_program = "/usr/bin/curl -o /dev/null " . $listmail_url . "/bounce.php";
You may need to try other alternatives or speak with your host about making one of these programs available to you.
