Many experts and regulators want I.T. systems to require regular passwords changes.   Active Directory provides support for expiration warning and mandatory reset.   But this policy becomes problematic f the user connects through an interface that does not provide expiration warnings and facilitates password changes.   We currently have some offsite users for whom SmarterMail is their primary connection the corporate network.   So we need SmarterMail to provide more complete integration with Active Directory, by warning users when their password is about to expire, and providing password change capability, whether initiated by the user in response to a warning or initiated by the system in response to an expiration.
