Password expiration. It should be a setting to require the users to periodically change their password and give them an reminder when the password are about to expire. When the password are expired the user should not be able to send mail and Worldclient should require a password change before opening the normal view.
MDaemon 13.5.0 allows an administrator to configure the maximum number of days before a user will have to change their password.
I've created a separate idea and included your comments.
I would like a small change to this function. The counting of days should start at 0 when you set maximum days value. This will prevent a lot of users to get locked out of their account before they get any warning about an expiring password.
You can also include a link to the correct webpage in the warning email and make this link available even if the users don't have Worldclient access.
Marcello, This is not exactly what you are looking for but it may help, MDaemon currently has the ability to delete accounts after X days of inactivity. Either way, I have created a separate idea for your request.

I would like to extend that idea to user expiration: ability to set a user/mailbox expiration date on a per user/per domain basis. Thank you.
