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: The POP subscriber's username The
mail drop for the POP subscriber (relative to the POP directory) The
POP subscriber's password generated by popwrd(8) The remote user al-
lowed to make remote POP (RPOP) connections
This database is an ASCII file. Each field within each POP sub-
scriber's entry is separated from the next by a colon. Each POP sub-
scriber 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 supply-
ing 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::
[email protected],
[email protected]::::
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.
