qmail-pw2u - build address assignments from a passwd file
qmail-pw2u [ -/ohHuUC ] [ -cchar
]
qmail-pw2u 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-pw2u.
If you put the output of qmail-pw2u into
/var/qmail/users/assign, and then run qmail-newu,
qmail-lspawn will obey the assignments printed by qmail-pw2u.
WARNING: After changing any users, uids, gids, or home directories in
your passwd file, you must run qmail-pw2u and qmail-newu again
if you want qmail-lspawn to see the changes.
By default, qmail-pw2u 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, or (4)
user contains uppercase letters. 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
- Allowed users, one per line. If include exists, and user is
not listed in include, user is ignored.
- exclude
- 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 form
user:mailname1:mailname2:...
The addresses mailname1 and
mailname1-ext and mailname2 and so on
will be delivered to user.
WARNING: The addresses user and
user-ext will not be delivered to
user unless user is listed as one of the
mailnames.
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.
- append
- Extra assignments, printed at the end of qmail-pw2u's output.
- -o
- (Default.) Skip user if home does not exist (or is not
visible to qmail-pw2u). 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.
- -cchar
- Use char as the user-extension delimiter in place of -.
- -C
- Disable the user-extension mechanism.
- -/
- Use home/.qmail-/... instead of
home/.qmail-...
