Can't confirm this.

Using PHP-CLI 4.1.2 and procmail v3.22 the '_' key isn't set either
in $_ENV nor in $_SERVER.

When the script get's called from the commandline "_" in both: $_ENV and
$_SERVER is set properly.

To count it up there are more than 2 ways of getting the path of the actual
executed script. These are:

$_ENV['_']
$HTTP_ENV_VARS['_']
$_SERVER['_']
$_SERVER['argv'][0]		// C-style. Should work for cli AND cgi scripts AFAIK

Using getcwd() as I wrote before is not a good solution as I found out there are
differences wheter you use a cgi or cli version of php. Search for "does not change" on:
http://www.php-resource.de/manual.php?p=features.commandline


greets,
Bernhard
