netauth - Authorize network mail access
netauth [ options ] [ user … ]
Netauth is an administrator’s tool that manages network mail access. Network access is determined by the existence of a special file in each user’s $/adm directory, called “mailstop”. If mailstop exists, the user is denied network mail sending privileges. This tool simplifies and automates many tasks related to managing network mail access.
The administrator uses netauth to grant or deny network mail access for one or more local accounts. It can be used to automatically grant network access after a probationary period. Furthermore, netauth can report network access for any or all accounts.
Netauth takes the following options:
Reports net access status for all users.

Grants network access by deleting all mailstop files older than 30 days (the default), or older than n days if a numeric argument is given.
Since netauth is most often used from a cron process, it generates and mails a log of its activity to the root account.
