qmail-pw2user - build address assignments from a passwd
file
SYNOPSIS
qmail-pw2user [ -ohHuUbBC ] [ -cchar ]
DESCRIPTION
qmail-pw2user reads a V7-format passwd file from standard
input and prints a qmail-users-format assignment file.
A V7-format passwd file is a series of lines. Each line
has the format
user:password:uid:gid:gecos:home:shell
where user is an account name, uid and gid are the user id
and group id of that account, and home is the account's
home directory. password, gecos, and shell are ignored by
qmail-pw2user.
If you put the output of qmail-pw2user into
/var/qmail/users/assign, and then run qmail-newuser,
qmail-lspawn will obey the assignments printed by qmail-
pw2user. WARNING: After changing any users, uids, gids,
or home directories in your passwd file, you must run
qmail-pw2user and qmail-newuser again if you want qmail-
lspawn to see the changes.
RULES
By default, qmail-pw2user follows the same rules as qmail-
getpw. It skips user if (1) uid is zero, (2) home does
not exist, (3) user does not own home, (4) user contains
uppercase letters, or (5) user contains - characters. It
then gives each remaining user control over the basic user
address and all addresses of the form user-anything. A
catch-all user, alias, controls all other addresses.
You may change these rules by setting up files in
/var/qmail/users:
include
A list of allowed users, one per line. If include
exists, and user is not listed in include, user is
ignored.
exclude
A list of ignored users, one per line. If exclude
exists, and user is listed in exclude, user is
ignored.
mailnames
Replacement names for users. Each line has the
The addresses mailname1 and mailname1-ext and mail-
name2 and so on will be delivered to user. The
addresses user and user-ext will not be delivered
to user unless user is listed as one of the mail-
names.
A line in mailnames is silently ignored if the user
does not exist.
subusers
Extra addresses. Each line has the form
sub:user:pre:
sub will be handled by home/.qmail-pre, where home
is user's home directory; sub-ext will be handled
by home/.qmail-pre-ext.
OPTIONS
-o (Default.) Skip user if home does not exist. Skip
user if home is not owned by user.
-h Stop if home does not exist. This is appropriate
if every user is supposed to have a home directory.
Skip user if home is not owned by user.
-H Do not check the existence or ownership of home.
-U (Default.) Skip user if there are any uppercase
letters in user.
-u Allow uppercase letters in user.
-B (Default.) Skip user if it contains -.
-b Allow - in user.
-cchar Use char as the user-extension delimiter in place
of -.
-C Disable the user-extension mechanism.
