Are you referring to integrating the Tuxedo Webmail with a MagicMail system? If so, we are still working on this functionality. Our first release of Tuxedo is meant to be a standalone product. With our next release, we are planning on adding support for easy integration with a MagicMail system. This should include adding features like modifying whitelists, blacklists and various other spam settings which MagicMail currently supports.
