I added functions to “functions.php” in my theme:
I’m not a PHP developer and I’m not a WordPress expert, so I’m sure it’s far from perfect, but here is my code:
function custom_bbp_notify_topic_subscribers( $reply_id = 0, $topic_id = 0, $forum_id = 0, $anonymous_data = false, $reply_author = 0 ) {
// Bail if subscriptions are turned off
if ( !bbp_is_subscriptions_active() ) {
return false;
}
/** Validation ************************************************************/
$reply_id = bbp_get_reply_id( $reply_id );
$topic_id = bbp_get_topic_id( $topic_id );
$forum_id = bbp_get_forum_id( $forum_id );
/** Topic *****************************************************************/
// Bail if topic is not published
if ( !bbp_is_topic_published( $topic_id ) ) {

}
/** Reply *****************************************************************/

if ( !bbp_is_reply_published( $reply_id ) ) {
return false;
}
// Poster name
$reply_author_name = bbp_get_reply_author_display_name( $reply_id );
/** Mail ******************************************************************/

remove_all_filters( 'bbp_get_reply_content' );
remove_all_filters( 'bbp_get_topic_title' );
// Strip tags from text and setup mail data
$topic_title = strip_tags( bbp_get_topic_title( $topic_id ) );
$reply_content = strip_tags( bbp_get_reply_content( $reply_id ) );
$reply_url = bbp_get_reply_url( $reply_id );
$blog_name = wp_specialchars_decode( get_option( 'blogname' ), ENT_QUOTES );
// For plugins to filter messages per reply/topic/user
