And here it is another possible workaround:

Solved – BuddyPress Smtp Settings

[etatus]

Hi, I’m trying to get SMTP and Buddypress work together too and I find here the cause and a possible workaround. I didn’t test yet, so if you try first, please let us now if it works.

I found a workaround to avoid the creation of duplicate activities for the same cpt post on updating.

function me_activity_parse_args_filter( $args = array() ) {     
    if ( !empty( $args['type'] ) && $args['type'] == 'new_your-cpt' ) {
                $activities = bp_activity_get(array(
                        'max' => 1,
                        'filter' => array(
                        'action' => 'new_your-cpt',
                        'secondary_id' =>  $args['secondary_item_id'],
                        ),
                ) );
                if (count($activities['activities'])==0) { // The cpt post doesn't have activity yet, so we set the group information
                        $args['component'] = 'groups'; // You could set this as 'component_id' in bp_activity_set_post_type_tracking_args
                        if ( !empty(bp_get_current_group_id()) ) $args['item_id'] = bp_get_current_group_id();
                        if (empty($args['content'])) $args['content'] = ' ';  // To make sure content filter applies afterwards 
                } else { // Activity already exists
                        $args['type'] = false; // Delete duplicate activity
                }
    }     
    return $args;
}
add_filter('bp_after_activity_add_parse_args', 'me_activity_parse_args_filter',10,1);

Here is another approach. I dont like it at all because you cannot check a custom post type (you dont have the activity object). But it works.

function me_filter_bp_activity_item_id_before_save( $item_id ) { 
    if ( !empty(bp_get_current_group_id()) ) $item_id = bp_get_current_group_id();
    return $item_id ; 
}; 
         
add_filter( 'bp_activity_item_id_before_save', 'me_filter_bp_activity_item_id_before_save', 10, 1 );

BTW: The value 1 seems to be the default blog ID.

In this thread @imath explains that:

Custom Post Type Support for Activity

I’m also interested in solving this problem (I think the number 1 is actually the user id). The only way I could find is to use bp_before_activity_add_parse_args filter:

function me_activity_parse_filter( $cpt ) {
    if ( $cpt['type'] == 'your_custom_type' ) {
        $cpt['item_id'] = bp_get_current_group_id();
    }     
    return $cpt;
}
add_filter('bp_before_activity_add_parse_args', 'me_activity_parse_filter');

However, if the cpt post is updated a new activity is created instead updating the original one…

Note that in bp_activity_set_post_type_tracking_args I have
'component_id' => 'groups',

Maybe @imath can help us to solve this issue.
