NAME

IndiMail - A Multi-host distributed Mail Server

DESCRIPTION

IndiMail is an messaging platform built using following packages

• qmail

• serialmail

• qmailanalog

• dotforward

• fastforward

• mess822

• daemontools

• ucspi-tcp

• Courier IMAP/POP3

• Bogofilter - A Bayesian Spam Filter

• Fetchmail

other useful software which are needed on a typical email server

• pack

• unpack

• altermime

• ripmime

• flash

Apart from providing ESMTP, IMAP, POP3 service, IndiMail provides Management of Virtual domains. IndiMail works on both 32 / 64 bit Unix platforms.

IndiMail consists of two packages.

The indimail-mta package which provides

o MTA, SMTP, QMQP, QMTP o daemontools package o ucspi-tcp package o bogofilter spam filter o fetchmail mail retrieval package

The indimail-mta package can be installed and function without the indimail package. If it finds the libindimail shared library, indimail-mta works seamlessly with virtual domains configured locally or on multiple hosts. This it does by dynamically loading the libindimail.so shared library by reading the control file libindimail or accessing the environment variable VIRTUAL_PKG_LIB.

The indimail package provides

o libindimail shared library o courier-imap for IMAP/POP3 o checkpassword or PAM authentication modules for IMAP/POP3 o virtual domain management. o vdelivermail local delivery agent.

The indimail package requires indimail-mta package to be installed. In fact, if you install indimail package using apt-get, yum/dnf, indimail-mta package will be automatically installed.

IndiMail provides qmail-remote / qmail-local, proxyimap & proxypop3 which are user-location aware (on which server the user's mailbox lies). This gives IndiMail the ability to distribute the users across multiple hosts using standard non-proprietary protocols detailed in standard RFCs. The other use of user-location aware property is to have a single domain consisting of a heterogeneous email server environment (with some users on MS Exchange and some on Lotus Notes some on IndiMail). To distribute mails for users across multiple hosts, IndiMail uses qmail-remote(8). qmail-remote(8) gives the ability to distribute the mails using SMTP or QMTP. You can use the ROUTES environment variable to "smtp" or "qmtp" to choose the protocol. You can have multiple hosts hosting a domain placed geographically anywhere and tied up by IndiMail. The architecture does not force a filesystem architecture like NFS to be used to distribute the users. In other words, IndiMail allows you to extend a domain across multiple servers and hence provide the ability to scale to any number of users. Such a domain which is extended across multiple servers is called a distributed domain. A distributed domain consists of multiple mailstore and one or many MySQL servers. A mailstore is a host which has the user's mail storage in Maildir. The MySQL servers hold user information like path of the Maildir, user privileges, user aliases and forwardings, user's mailstore. The MySQL servers can be present on the mailstores itself or as individual servers or as a single server holding information for all users on all mailstores. The configuration is flexible and is left to the user so that one can optimize on cost or performance.

When an IMAP or POP3 client logs in through proxyimap/proxypop3, the following takes place:

• The proxy analyzes the login sequence

• Extracts the user name of the user trying to login

• Does a lookup query on the local server to find out the server having the mailbox of the user attempting the login. This lookup service (named inlookup(8)) runs on all mailbox servers and accepts requests through a well defined FIFO.

indimail-mta uses a highly modified qmail and provides all features needed in a modern MTA. However, all features have been added by re-using the functions/libraries provide by stock qmail (stralloc, substdio, alloc, str, env, etc). Detailed feature list of IndiMail is provided on the website http://www.indimail.org

IndiMail has two databases. For most purposes, IndiMail can function with just the local database. For a distributed environment, IndiMail requires two databases.

local database - Contains all user information, attributes

[step]
central database - Used only when configured as a distributed domain. This database is refered to as 'clusterinfo'.

For a non-distributed architecture, you need a local MySQL database. To connect to this MySQL database, you need to have a control file host.mysql. This control file contains the IP address or hostname of the MySQL database corresponding to the local database. If the control file host.mysql is missing, programs will use localhost to connect to MySQL. One can also use host:user:password:socket/port[:ssl] format for host.mysql.

The local database consists of the following tables

indimail

[step]
indibak

[step]
valias

[step]
vlimits

[step]
userquota

[step]
relay

[step]
lastauth

A distributed domain in IndiMail is achieved by having a central MySQL database called clusterinfo. clusterinfo stores information about the user's storage server (mailstore) and each mailstore's individual local MySQL database's connection parameters (host, user, password, socket or port, ssl/nossl). This database is also referred to as the central database. It consists of the following tables

hostcntrl

[step]
host_table

[step]
dbinfo

[step]
smtp_port

[step]
mgmtaccess

[step]
vpriv

The table hostcntrl has the fields user, domain and hostid. hostid is a unique identifier which needs to be assigned to every server on which email accounts need to be created. These servers are also called mailstores. The program hostcntrl(8) can be used to add, modify, delete entries to the table hostcntrl. The program vadduser(1) also adds user entries to this table. Each hostid needs to be mapped to an IP address. This is maintained in the table host_table. A program called vhostid(8) can be used to add, modify or delete entries in host_table.

To be able to access the central database, IndiMail programs need the following control files in the directory /etc/indimail/control

host.master

[step]
host.cntrl

These control file contains the IP address or hostname of the MySQL database corresponding to the central database. You can also use host:user:password:socket/port[:ssl] format for these control files. If you plan to have a master-slave MySQL architecture, you can have entry in host.master pointing to the MySQL master database and have entry in host.cntrl pointing to the MySQL slave database. With these control files, all indimail programs ensure that all writes go to the master database and reads happen only from the slave database. The control files host.master, host.cntrl can be overriden by the environment variables MASTER_HOST and CNTRL_HOST. One can also give host:user:password:mysql_socket/port[:ssl] as the format for host.master and host.cntrl.

IndiMail uses gethostid(3) and getaddrinfo(3) to figure out its identity. getaddrinfo(3) requires your hosts address to be either resolved by dns or be present in hosts(5) /etc/hosts. You can bypass gethostid(3) and getaddrifno(3) by have your hostid in /etc/indimail/control/hostid and your IP address in /etc/indimail/control/localiphost.

In a distributed setup, you can have multiple servers with each server having its own set of local users. The information for these users are stored in a MySQL database known as the local database. You can have multiple local databases with each database serving one email server. You can also club user information for multiple email servers in a single MySQL local database. This flexibility helps IndiMail achieve scalability. So apart from the user's location which is maintained in the central database, other user attributes like home directory, gecos, quota, access rights are maintained in another MySQL database called the local database.

Access to the individual local database by indimail programs is made easy by, having the parameters needed to connect to each of the MySQL local datbase, in a table called dbinfo, on the central database. The same information can be maintained in a control file /etc/indimail/control/mcdinfo. The file mcdinfo allows one to maintain and sync information about each and every mailstore on the dbinfo table. The updation depends on the timestamp of the mcdinfo file and dbinfo table. The moment mcdinfo is updated, the same information gets updated in the dbinfo table. The moment dbinfo gets updated, the file mcdinfo on all other mailstore (older than the dbinfo table) gets updated. The entries in dbinfo table / mcdinfo file can be seen by running the dbinfo(8) program. Whenever a new mailstore is added/removed, the entry for the mailstore and the corresponding MySQL local database needs to be added/removed in the dbinfo table or mcdinfo file. In short, the entries in the dbinfo table and the mcdinfo control file on all servers are kept in sync.

Depending on how IndiMail was configured during the build process, it can dynamically load the libmysqlclient library using dlopen(3), by reading the control file mysql_lib or the environment variable MYSQL_LIB environment variable. The advantage of such a build is the ability to use either MariaDB or MySQL client libraries as the library is not linked during the linking stage.

It may be noted that the connection to MySQL can be fine tuned by editing the file /etc/indimail/indimail.cnf. This file has [client] section that all indimail programs use. It also has [mysqld] section which is used my mysqld(8), if it is managed by supervise(8). You can also change the behaviour of the MySQL connections by setting enviroment variables. Please see the section on 'Environment Variables' to understand that.

In case you do not require a multi-host setup, IndiMail does not require central database. Programs just need to connect to the local database which can be configured by having the control file /etc/indimail/control/host.mysql.

Virtual Domains

IndiMail has an idea of email domains that are "local" and "virtual". Local domains are ones which primarily match against /etc/passwd. Virtual domains match against domains listed in the control file /etc/indimail/control/virtualdomains. IndiMail makes use of the /var/indimail/users/assign file and virtualdomains file. The users/assign file gets compiled into a users/cdb file. It is a hashed database to speed searches for patterns. If a pattern is matched then IndiMail delivers the email to the directory defined in the file using the uid and gid which is also defined. IndiMail makes use of this method to deliver all virtual domain email as the single uid/gid indimail/indimail. It also uses it to take delivery instructions from /var/indimail/domains/<virtualdomain>/.qmail-default file. Once qmail-local gets the information from the users/assign file it performs standard .qmail file processing in the directory. Normal .qmail-<user> files can be used for forwarding, aliases or invoking programs such as ezmlm. If no matches are found qmail-local looks for a .qmail-default file. This is the last stage in qmail-local's delivery mechanism. qmail-local uses this file to invoke the vdelivermail program. This program takes two parameters, the first is not used (it is there for backward compatibility). The second parameter is the default delivery if a virtual domain user can not be found. Basically, it can be one of the following

Full path to a indimail user directory

[step]
email address to forward email to

[step]
the string bounce-no-mailbox to bounce the email back to the sender.

[step]
Address in SMTPROUTE format to which vdelivermail should use SMTP to deliver the mail. e.g.

indimail.org:192.168.1.55:25

where indimail.org is the local domain, 192.168.1.55 is the IP address of an SMTP server for indimail.org and 25 is the SMTP port.

Virtual Domain Directory Structure Layout

IndiMail uses an adaptive directory structure based on a table dir-control which is automatically managed by the core programs vadduser(1) and vdeluser. The basic idea is to break up the user Maildir directories across multiple directories and sub directories so that there are never more than 100 user directories in a single directory.

In a single file system, the default directory setup allows for 62 directories in 3 levels and 100 user directories per directory. The total number of user directories is equal to (62 * 100) + (62 * 62 * 100) + (62 * 62 * 62 * 100) = over 24 million directories per filesystem. This should be more than sufficient for any site and probably goes beyond the technology of directory structures.

If you are going to be storing large numbers of user directories, make sure you set your file system to have a higher than normal percentage of inodes.

IndiMail will automatically create these directories and sub directories as needed and populate each directory with up to 100 user accounts. As soon as a directory reaches 100 users it will create the next directory or sub directory and store the new users directory there.

You can use the vreorg(8) program to recreate the dir-control table.

STARTUP

IndiMail uses svscan(8) to start, monitor and restart (if neccessary) all services needed for proper functioning of email server. On most Linux systems, svscan is installed as a systemd(1) service. On systems that uses the traditional init(1), svscan is installed as an entry in /etc/inittab. Some of the later systems come with upstart(8), in which case, svscan is installed in /etc/event.d. On MacOS the file indimail.plist in the directory /System/Library/LaunchDaemons is used by launchctl to start IndiMail.

The program initsvc(1) can be used to enable svscan to get automatically started on system boot. All services are installed in /service which each directory representing a service. These services are started and monitored by supervise(8). The table below gives all the service directories in /service. You can use the svps(1) program to list the status of all services.

You can use svc(8) to start / stop individual services. To disable / enable all services, you can use the initsvc(8) command.

IndiMail attempts to be as portable as possible across different system. You can use any of the following two commands to start IndiMail on all systems

 # service indimail start
 or
 # initsvc -on

POST Execution Handle

Some indimail programs have a post execution handle. A post execution handle is a program with the same name as that of the calling program but in the directory /var/indimail/libexec. On successful completion, such programs execute the handle program and return the status of the called handle program. If the handle program is not accessible, the return status is zero. Normally, the handle program always gets executed from /var/indimail/libexec directory, but you can override the program called by setting the environment variable POST_HANDLE.

Post execution handle is useful when you want to achieve a task that is beyond the scope of IndiMail's programs. These handle help you to extend the functionality of indimail programs when adding domains, adding users, modifying a domain or modifying a user. These handles are passed arguments depending on the arguments passed to the original program. See the section on POST HANDLE in the man page for the programs mentioned below having post execution handle.

Programs that support this post execution handle are vadddomain(1), vdeldomain(1), vrenamedomain(1), vadduser(1), vdeluser(1), vrenameuser(1), vmoveuserdir(1), vpasswd(1).

The distribution includes two post execution handles vadddomain and vadduser.

PROGRAMS

Download/Repository

IndiMail provides the package in both source and binary forms. Installation from the source requires you to download other packages from the respective websites apart from the indimail core package. The indimail package contains a patch directory which allows you to add features to qmail, ucspi-tcp, courier-imap, etc. Details for building IndiMail from source can be read in the INSTALL document provided with the source package. Many users may find this complicated and hence binary packages are also provided which can be downloaded from the RPM repo mentioned below.

Source Download - http://sourceforge.net/projects/indimail/
Git Repository - http://indimail.git.sourceforge.net/
Stable RPM Repo - http://download.opensuse.org/repositories/home:/indimail/
Raw RPM Repo - http://download.opensuse.org/repositories/home:/mbhangui/

IndiMail uses openSUSE Build service to build the RPM whenever there is a new release. Currently, the list of supported distributions for IndiMail RPM (for both 32 and 64 bit) are
