5 POP \- POP database of subscribers
|
|
6 .SY
|
|
7 /usr/spool/pop/POP
|
|
8 .DE
|
|
9 The POP database has exactly the same format as the \fIBBoards\fR\0(5)
|
|
10 database,
|
|
11 although many fields are unused.
|
|
12 Currently,
|
|
13 only four fields are examined:
|
|
14
|
|
15 .nf
|
|
16 .ta \w'encrypted password 'u
|
|
17 \fIfield\fR \fIvalue\fR
|
|
18 name the POP subscriber
|
|
19 primary file the maildrop for the POP subscriber
|
|
20 (relative to the POP directory)
|
|
21 encrypted password the POP subscriber's password
|
|
22 network address the remote user allowed to RPOP
|
|
23 .re
|
|
24 .fi
|
|
25
|
|
26 This is an ASCII file. Each field within each POP subscriber's entry
|
|
27 is separated from the next by a colon.
|
|
28 Each POP subscriber is separated from the next by a new-line.
|
|
29 If the password field is null, then no password is valid.
|
|
30
|
|
31 To add a new POP subscriber,
|
|
32 edit the file adding a line such as
|
|
33
|
|
34 .ti +.5i
|
|
35 mrose::mrose:::::::0
|
|
36
|
|
37 Then, use \fIpopwrd\fR to set the password for the POP subscriber.
|
|
38 If you wish to allow POP subscribers to access their maildrops without
|
|
39 supplying a password (by using privileged ports),
|
|
40 fill\-in the network address field, as in:
|
|
41
|
|
42 .ti +.5i
|
|
43 mrose::mrose:::mrose@nrtc-isc::::0
|
|
44
|
|
45 which permits \*(lqmrose@nrtc\-isc\*(rq to access the maildrop for the POP
|
|
46 subscriber \*(lqmrose\*(rq.
|
|
47 Multiple network addresses may be specified by separating them with commas,
|
|
48 as in:
|
|
49
|
|
50 .ti +.5i
|

|
|
53 To disable a POP subscriber from \fIreceiving\fR mail,
|
|
54 set the primary file name to the empty string.
|
|
55 To prevent a POP subscriber from \fIpicking\-up\fR mail,
|
|
56 set the encrypted password to \*(lq*\*(rq
|
|
57 and set the network address to the empty string.
|
|
58
|
|
59 This file resides in home directory of the login \*(lqpop\*(rq.
|
|
60 Because of the encrypted passwords,
|
|
61 it can and does have general read permission.

69 Appropriate precautions must be taken to lock the file against changes
|
|
70 if it is to be edited with a text editor.
|
|
71 A \fIvipop\fR program is needed.
