  • you have to set the priority to NULL

    i don’t know this plugin, found your question on google ??

    when there are no option to set the priority to NULL, you have look into the code for something like this

    $result .= $this->HeaderLine('X-Priority', $varforpriority);

    and set $varforpriority to NULL

    this will remove the header
