[Top] [Contents] [Index] [ ? ] Vmailmgr Configuration Files 1. General Information 2. Configuration Files _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 1. General Information 1.1 Search Order 1.2 File Types 1.3 Command Execution _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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: 1. The domain-local configuration directory 2. The user-local configuration directory 3. 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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). _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 2.

Note that this has nothing to do with "real" users, for which the password file is determined by the system libraries. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 2.24 postmaster-aliases Type list Default `mailer-daemon' `postmaster' `root' Used By vsetup Description A list of aliases to the postmaster email address to set up when creating a new virtual domain with the vsetup command. This should always contain both `postmaster' and `mailer-daemon' (required by the RFCs), and should usually contain `root'. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 2.25 postmaster-email Type string Default `postmaster@' Used By vsetup Description Identifies the email address of the entity responsible for the administration of the (virtual) host when building the 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 is filled in by vdeliver. If this is set to `postmaster', a mail loop will result and all mail to this address will bounce. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 2.26 qmail-root Type string Default `/var/qmail' Used By checkvpw, vdeliver, vmailmgrd Description Specifies the location of the base directory of your qmail install. Set this to whatever you put into `conf-home' when you built and installed qmail. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 2.27 separators Type string Default `@:' Used By checkvpw (global only) Description Identifies the set of valid separators within a user login name between the virtual user name and virtual domain name when logging in via checkvpw. For example, if separators contains `@:' then `user@domain' and `user:domain' are equivalent POP mailbox names. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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/'. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 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. _________________________________________________________________ [ < ] [ > ] [ << ] [ Up ] [ >> ] [Top] [Contents] [Index] [ ? ] 2.35 vsetup-pre Type executable Default Empty Used By vsetup Description This list is executed before the vsetup command makes any changes. _________________________________________________________________ [Top] [Contents] [Index] [ ? ] Table of Contents 1.
