BuddyPress 2.5 introduced some wonderful email functionality. In order to do this, it bypasses WordPress’ default email methods. This means that any filters you applied to the <code>wp_mail_from</code> and <code>wp_mail_from_name</code> filters don’t work with emails sent by BuddyPress. This plugin translates those filters into something BuddyPress can use.
