VPOP3 includes an optional ‘Finger’ server.
If the VPOP3 finger server is enabled, then by default it will only reveal user email addresses and whether or not they have any waiting email, such as:
UserId: paul
Email Address: paul@domain.com
User has waiting messages
Note that it is possible to limit the IP address which will have access to this information by going to the Services -> Finger page, and setting the Access Restrictions.
It is also possible to change the information returned by the finger server, by changing the Finger Results Template on the Finger Server settings page
It is possible to add to the information returned by VPOP3’s Finger server in two ways.
Tthe administrator An Administrator is a VPOP3 user who is allowed to change VPOP3 settings, add/remove users, view queued messages etc. can create an entry containing User Information. This can be used to contain information such as the user’s telephone extension, job title etc. This entry is created by going to the User Advanced settings page and editing the Finger - User Information text. You can also change this information by directly editing the USERINFO.TXT file in the user’s mail directory. If this file does not exist, then VPOP3 will simply not add the information to the output of a Finger query. (Note VPOP3 will only return with the User Information if the Finger query is verbose - see your Finger software’s documentation for how to set this)
The user or administrator can create an entry containing a User Plan. This can be used to contain information which the user wants to make public, such as their interests, current job role etc. This entry is created by the administrator by going to the User Advanced settings page and editing the Finger - User Plan text, or by the user by sending a message to the Mailer_Daemon or editing it through the WebMail Settings. You can also change this information by directly editing the USERPLAN.TXT file in the user’s mail directory. If this file does not exist, then VPOP3 will simply not add the information to the output of a Finger query.
The user can also query their current plan by sending a message to Mailer_Daemon.
