Hallo und Danke für die Antworten, habe dadurch die Datei gefunden in der das geändert werden kann.
in der \wp-includes\pluggable.php ab Zeile 316
war dann ganz einfach...
>>>>>>>>>>
// From email and name
// If we don't have a name from the input headers
if ( !isset( $from_name ) )
$from_name = 'Natur-Make-Up'; [COLOR=#b22222] statt Wordpress[/COLOR]
/* If we don't have an email from the input headers default to wordpress@$sitename
* Some hosts will block outgoing mail from this address if it doesn't exist but
* there's no easy alternative. Defaulting to admin_email might appear to be another
* option but some hosts may refuse to relay mail from an unknown domain. See
* http://trac.wordpress.org/ticket/5007.
*/
if ( !isset( $from_email ) ) {
// Get the site domain and get rid of www.
$sitename = strtolower( $_SERVER['SERVER_NAME'] );
if ( substr( $sitename, 0, 4 ) == 'www.' ) {
$sitename = substr( $sitename, 4 );
}
$from_email = 'blog@' . $sitename; [COLOR=#b22222]statt wordpress@[/COLOR]
}

und gut war's
