I cannot seem to get Mailhandler to create the nodes during a cron run. I can get it to do everything I want when I use the Import button on my Mailhandler content type. Here is my feeds export:

$feeds_importer = new stdClass();
$feeds_importer->disabled = FALSE; /* Edit this to true to make a default feeds_importer disabled initially */
$feeds_importer->api_version = 1;
$feeds_importer->id = 'test_importer';
$feeds_importer->config = array(
'name' => 'test importer',
'description' => 'test importer',
'fetcher' => array(
'plugin_key' => 'MailhandlerFetcher',
'config' => array(
'filter' => 'MailhandlerFiltersNodes',
),
),
'parser' => array(
'plugin_key' => 'MailhandlerParser',
'config' => array(
'available_commands' => 'status: 1',
'authenticate_plugin' => 'MailhandlerAuthenticateDefault',
),
),
'processor' => array(
'plugin_key' => 'FeedsNodeProcessor',
'config' => array(
'expire' => '-1',
'author' => '6',
'authorize' => 1,
'mappings' => array(
0 => array(
'source' => 'subject',
'target' => 'title',
'unique' => FALSE,
),
1 => array(
'source' => 'body_text',
'target' => 'body',
'unique' => FALSE,
),
),
'update_existing' => '0',
'input_format' => 'filtered_html',
'skip_hash_check' => 0,
'bundle' => 'blog',
),
),
'content_type' => 'mailhandler_source',
'update' => 0,
'import_period' => '0',
'expire_period' => 3600,
'import_on_create' => 1,
'process_in_background' => 0,
);
