The module is a pre-beta of automated cpanel registration that will be available in the Cpanel Emal for Mambo Component that should allow users of your mambo website to register cpanel email accounts, and email management for the website admin through mambo administration.(backend)
The current module just has the registration feature and provides webmail through @mail (atmail looks great! btw)
