11: .SH DESCRIPTION
12: The POP database has exactly the same format as the \fIBBoards\fR\0(5)
13: database,
14: although many fields are unused.
15: Currently,

24: encrypted password the POP subscriber's password
25: network address the remote user allowed to RPOP
26: .re
27: .fi
28:
29: This is an ASCII file. Each field within each POP subscriber's entry
30: is separated from the next by a colon.
31: Each POP subscriber is separated from the next by a new-line.
32: If the password field is null, then no password is valid.
33:
34: To add a new POP subscriber,
35: edit the file adding a line such as
36:
37: .ti +.5i
38: mrose::mrose:::::::0

43: fill\-in the network address field, as in:
44:
45: .ti +.5i
46: mrose::mrose:::mrose@nrtc-isc::::0
47:
48: which permits \*(lqmrose@nrtc\-isc\*(rq to access the maildrop for the POP
49: subscriber \*(lqmrose\*(rq.
50: Multiple network addresses may be specified by separating them with commas,
51: as in:
