I found that emails didn’t have the correct header set for ‘Return-path’.  While technically the header should be case insensitive, I found changing it to ‘Return-Path’ fixed the issue.  This may be specific to my circumstances (PHP version, WP version, email server, email client, etc.) , but I figured I would bring it up.
