NAME
  pop - POP database of subscribers

SYNOPSIS
  /usr/spool/pop/POP

DESCRIPTION
  The POP database contains the following entry for each POP subscriber:

       name::primary_file:encrypted_passwd:: user@<client_address>::::0

  The fields represent the following:

  name
      The POP subscriber's username

  primary_file
      The mail drop for the POP subscriber (relative to the POP directory)

  encrypted_passwd
      The POP subscriber's password generated by popwrd(8)

  user@<client_address>
      The remote user allowed to make remote POP (RPOP) connections

  This database is an ASCII file.  Each field within each POP subscriber's
  entry is separated from the next by a colon.	Each POP subscriber is
  separated from the next by a new-line.  If the password field is null, then
  no password is valid.

  To add a new POP subscriber, edit the file adding a line such as the
  following:

       mrose::mrose:::::::0i

  Then, use popwrd to set the password for the	POP  subscriber.  If you wish
  to allow POP subscribers to access their maildrops without supplying a
  password (by using privileged ports), fill-in the network address field, as
  in:

       mrose::mrose:::mrose@nrtc-isc::::0

  which permits "mrose@nrtc-isc" to access the maildrop for  the  POP
  subscriber "mrose".  Multiple network addresses may be specified by
  separating them with commas, as in:

       dave::dave:9X5/m4yWHvhCc::dave@romano.wisc.edu,dave@rsch.wisc.edu::::

  To disable a POP subscriber from receiving mail, set the primary file name
  to the empty string.	To prevent a  POP  subscriber  from picking-up mail,
  set the encrypted password to "*" and set the network address to the empty
  string.

  This file resides in home directory of the login "pop."  Because of the
  encrypted passwords, it can and does have general read permission.
