If you go away, you can leave a forwarding number. Users can file mail if they desire. Messages are automatically erased from the mailbox after two weeks, if they have been read at least once. Users like this feature as it frees them from having to worry about disposing of old mail. File protection concepts are built in.
Every message has an owner.
You can check if someone has read the mail you sent him. Other status information is also available, such as whether he has logged in today, etc. You can also record a message to be read to anyone who asks about you. So, for example, if you are out of town for a week, you can leave a message saying so. The system provides extensive editing facilities which are mostly unused as the users think they are too complex.
