Vmailmgr Configuration Files
1. General Information
1.1 Search Order
The system will look for the configuration files listed below in one of
the following three locations, in the order they are listed:
- The domain-local configuration directory
- The user-local configuration directory
- The global configuration directory
The global configuration directory is set to `/etc/vmailmgr' by
default.
The user-local and domain-local configuration directories (for now, one
and the same) are a subdirectory, named `.vmailmgr' by default, of
either the user's home directory or the domain subdirectory.
If a file matching the configuration name is found in one of the local
directories, the search stops and it is not searched for in any
higher up directories.
1.2 File Types
Each of the configuration files falls into one of the following types:
- String
A single line is read from this type and used as-is with no conversion.
All data after the first line is ignored.
- Directory
A single line is read from this type.
If it does not have a trailing slash (`/'), one is appended.
All data after the first line is ignored.
- Number
A single line is read from this type and converted to an unsigned
integer.
If the conversion succeeds, the value is used.
All data after the first line is ignored.
- List
Each line of the file is read, stripped of leading and trailing
whitespace, and treated as a separate value.
Lines that contain only whitespace (ie blank lines) or lines beginning
with a pound symbol (`#') are ignored.
- Executable
If the execute bits on the file are set, it is treated as an executable
file and is executed with no interpretation by vmailmgr.
The the Command Execution section below for details.
All lines are stripped of any leading or trailing white space.
Configuration files marked as `(global only)' are read
before any user-level processing occurrs, and so are not functional in
the user-level configuration.
1.3 Command Execution
The following rules apply to executing a single command or a list of
commands.
The executables are searched in reverse order of the configuration
files.
That is, the global setting is used first, and then the local settings.
If the named file either does not exist in a directory or is not
executable, that directory is skipped.
A command exit code of `99' indicates that the command completed
successfully but no further commands should be executed.
All other non-zero exit codes are treated as an error and will cause the
invoking program to stop with the same error code.
For `vdeliver', an error exit of 111 will be passed up to qmail as a
temporary error, and an error exit of 100 will be passed up as a
permanent failure.
See the `qmail-command' man page for full details on delivery error
codes.
For `checkvpw', any non-zero exit code (except as described above)
will cause authentication to fail.
The following environment variables will be set (where applicable):
- `HOME'
- The home directory of the real user.
- `MAILDIR'
- The mail directory of the real or virtual user.
- `USER'
- The real user's name.
- `VUSER'
- The virtual user's name.
For base user logins, this is blank, and all the following items
prefixed with `VUSER_' are not set.
- `VUSER_CTIME'
- The virtual user's creation time (or "0" if unknown).
- `VUSER_EXPIRY'
- The virtual user's expiry time (or "-" if not applicable).
- `VUSER_HARDQUOTA'
- The virtual user's total size hard quota (in bytes, or "-" if not applicable).
- `VUSER_MSGCOUNT'
- The virtual user's message count limit (or "-" if not applicable).
- `VUSER_MSGSIZE'
- The virtual user's message size limit (or "-" if not applicable).
- `VUSER_PERSONAL'
- The virtual user's personal data.
- `VUSER_SOFTQUOTA'
- The virtual user's total size soft quota (in bytes, or "-" if not applicable).

postmaster aliases above.
If this value ends with a trailing `@', the value of
`/var/qmail/control/me' is filled in for the host name.
If no `@' is present, the current virtual host name

For example, if separators contains `@:' then `user@domain' and
`user:domain' are equivalent POP mailbox names.
2.28 socket-file
- Type
- string
- Default
- `/tmp/.vmailmgrd'
- Used By
- vmailmgrd, checkvpw, vdeliver, and the CGI programs
- Description
- Identifies the file name of the local socket used to
communicate between the vmailmgr daemon and the other programs.
Warning: Changing this in the local configuration directories
will cause vdeliver to fail.
2.29 user-dir
- Type
- directory
- Default
- `users'
- Used By
- vmailmgrd and command-line programs
- Description
- Identifies the subdirectory from the virtual domain directory in which a
virtual user's maildir will be created.
Since this maildir is recorded in the password table, it does not have
to be the same for each user within a domain.
This is prefixed with `./' before it is used in the password table.
2.30 user-dir-bits
- Type
- Default
- `0'
- Used By
- vmailmgrd and command-line programs when creating new users.
- Description
- See section 2.31 user-dir-slices.
2.31 user-dir-slices
- Type
- Default
- `0'
- Used By
- vmailmgrd and command-line programs when creating new users.
- Description
- `user-dir-bits' and `user-dir-slices' work together. When creating a
new user directory name, a hash code is generated on the name of the
new user. This hash code is split into `user-dir-slices' pieces, each
`user-dir-bits' bits long. Each of these pieces is translated to an
ASCII string by converting the binary code to hexadecimal. The
resulting user directory name is then composed of:
- the base users directory, followed by a `/'
- each of the string pieces, each followed by a `/'
- the user's name
For example, with `user-dir-bits' set to 6 and
`user-dir-slices' set to 1, a user
named `c' maps to a directory name of `users/2f/c/'.
2.32 vdeliver-postdeliver
- Type
- executable
- Default
- Empty
- Used By
- vdeliver
- Description
- This list is executed after the delivery is successfully
completed.
Since vdeliver expects `USER' and `HOME' to be set, it does
not set them itself.
If the command returns with an error code, a warning is printed, but
delivery does not fail, as failure would lead to duplicates.
2.33 vdeliver-predeliver
- Type
- executable
- Default
- Empty
- Used By
- vdeliver
- Description
- This list is executed before the delivery is attempted, but
after the virtual user information is looked up.
Since vdeliver expects `USER' and `HOME' to be set, it does
not set them itself.
2.34 vsetup-post
- Type
- executable
- Default
- Empty
- Used By
- vsetup
- Description
- This list is executed after the vsetup command has sucessfully done
everything else.
2.35 vsetup-pre
- Type
- executable
- Default
- Empty
- Used By
- vsetup
- Description
- This list is executed before the vsetup command makes any changes.
