qmail-users - assign mail addresses to users
The file /var/qmail/users/assign assigns the local part of mail addresses to users. For example,
=joe.shmoe:joe:503:78:/home/joe:::
says that mail for joe.shmoe should be delivered to user joe, with uid 503 and gid 78, as specified by /home/joe/.qmail.
Assignments fed to qmail-newu will be used by qmail-lspawn to control qmail-local’s deliveries. Use qmail-newu (8) to generate users/assign.cdb from users/assign. A change to /var/qmail/users/assign will have no effect until qmail-newu is run.
/var/qmail/users/assign is a series of assignments, one per line. It ends with a line containing a single dot. Lines must not contain NUL.
A simple assignment is a line of the form
=local:user:uid:gid:homedir:dash:ext:
Here local is an address; user, uid, and gid are the account name, uid, and gid of the user in charge of local; and messages to local will be controlled by homedir/.qmaildashext.
If there are several assignments for the same local address, qmail-lspawn will use the first one.
local is interpreted without regard to case.
A wildcard assignment is a line of the form
+loc:user:uid:gid:homedir:dash:pre:
This assignment applies to any address beginning with loc, including loc itself. It means the same as
=locext:user:uid:gid:homedir:dash:preext:
for every string ext.
A more specific wildcard assignment overrides a less specific assignment, and a simple assignment overrides any wildcard assignment. For example:
+:alias:7790:2108:/var/qmail/alias:-::
+joe-:joe:507:100:/home/joe:-::
=joe:joe:507:100:/home/joe:::
The address joe is handled by the third line; the address joe-direct is handled by the second line; the address bill is handled by the first line.
