indimail-virtualdomains Introduction

Messaging Platform based on indimail-mta for MTA (modified qmail), IndiMail-VirtualDomains for Virtual Domains, Courier-IMAP for IMAP/POP3

• Look at README-indimail for details on IndiMail, indimail-mta. indimail needs indimail-mta to be installed, instructions for installing the same are included below. You can also read this README for details specific to installing indimail-mta alone.
• Look at README-CLUSTER for details on setting up an IndiMail Cluster. You don't need this if you don't need to distribute your domain across multiple servers. If you have a decent network, you don't require this. However, an IndiMail cluster allows you to exploit your good last-mile connectivity.
• Look at INSTALL for very detailed Source Installation instructions. You may not need that if you follow instructions below in this document itself.
• Look at INSTALL-MYSQL for instructions on configuring a MySQL/MariaDB server for IndiMail.
• Look at INSTALL-RPM for instructions on setting up IndiMail using RPM or Debian packages
• Look at Quick-INSTALL for instructions on installation and setup of an IndiMail server.
• Look at INSTALL-MINI for instructions on setting up an MINI Indimail Installation which uses QMQP protocol. indimail-mini is part of the indimail-mta package. You can use this for diskless clients, small devices, SBCs like the Raspberry PI, to push mails to any server running IndiMail or indimail-mta.
• Look at QMTA for instructions on settig a minimal MTA that runs as a single daemon and uses minimal resources.
• Look at Docker/Podman for instructions on using docker / podman containers for indimail. The big advantage of using a docker / podman image is you can save your configuration with the docker commit .. or podman commit to checkpoint your entire build and deploy the exact configuration on multiple hosts.

README-indimail is a detailed wiki for indimail-virtualdomains.

This document contains instructions for building indimail-virtualdomains from source. indimail-virtualdomains compiles and runs on all linux distros (Fedora, Debian, openSUSE, SLES), Arch Linux, Gentoo, Alpine Linux, FreeBSD and Mac OS X. Let me know if you want it on any other OS not mentioned in this document. The correct way to read this document is from top to bottom and follow the instructions serially. If you click on any link, you need to come back to this document.

To install you need to do the following

Building the Source - Compilation and Linking

The steps below give instructions to build from source. If you need to deploy indimail-mta on multiple hosts, it is better to create a set of RPM / Deb binary packages. Once generated, the package/packages can be deployed on multiple hosts. To generate RPM packages for all components refer to Create Local Binary Packages. This document contains instructions for building indimail-virtualdomains from source. indimail-virtualdomains compiles and runs on all linux distros, Arch Linux, Gentoo, FreeBSD and Mac OS X. Let me know if you want me to try it on any other OS.

You can also use docker / podman images to deploy indimail. Look at the chapter Docker / Podman Repository below on how to do that. The big advantage of using a docker / podman image is you can save your configuration with the docker commit .. or podman commit to checkpoint your entire build and deploy the exact configuration on multiple hosts.

Doing a source build can be daunting for many. There are total of 18 sub-packages to be built, out of which 6 (libdkim2, libsrs2, ucspi-tcp, courier-imap, indimail-mta, indimail) are required, 6 (bogofilter, bogofilter-wordlist, fetchmail, nssd, pam-multi, iwebadmin) are recommended and remaining 6 are optional. On Linux, you can always use the pre-built binaries from the DNF / YUM / APT repositories given in the chapter Binary Builds on OBS towards the end of this document.

Doing a source build requires you to have all the development packages installed. Linux distributions are known to be crazy. You will have different package names for different distirbutions. e.g.

db-devel, libdb-devel, db4-devel on different systems, just to get Berkeley db installed. There is an easy way out to find out what your distribution needs.

• For RPM based distribtions, locate your .spec file (e.g. indimail.spec in indimail-virtualdomains/indimail-x directory, libqmail/libqmail.spec). Open the RPM spec file and look for BuildRequires. This will tell you what you require for your distribution. If there is a specific version of development package required, you will find %if %else statements. Use dnf / yum / zypper to install your development package.
• For debian based distribution, locate your debian subdirectory (e.g. indimail-virtualdomains/indimail-x/debian, libqmail/debian). In this directory you will find files with .dsc extension. Look at the line having Build-Depends. Use apt-get install package to install the package. If your debian distribution has few libraries different than the default, you will find a .dsc filename with a name corresponding to your distribution. (e.g. indimail-Debain_10.dsc)

Note

This is a rough list of packages required. If you want the exact packages, look BuildRequires in the *.spec file or Build-Depends in the debian/control or debian/*.dsc files

Setup & Configuration

You are here because you decided to do a complete source installation. If you use source installation method, you need to setup various configuration and services. You can configure indimail/indimail-mta using /usr/sbin/svctool. svctool is a general purpose utility to configure indimail/indimail-mta services and configuration. At this point you should stop MySQL/MariaDB service if it is up.

You can also run the script create_services which invokes svctool to setup few default services to start a fully configured system. If you pass --add-boot argument to create_services, create_services will also put a systemd(1) unit file svscan.service in /lib/systemd/system. For FreeBSD systems, it will configure indimail to be started by rc(8) by creating a rc script in /usr/local/rc.d/svscan. For Darwin (Mac OSX), it will put a LaunchDaemon unit file in /Library/LauncDaemons. You can enable automatic later (detailed in the next section).

$ cd /usr/local/src/indimail-mta/indimail-mta-x
$ sudo ./create_services

The script create_services does the following.

1. Creates MySQL user 'indimail' with password 'ssh-1.5-'. This user has access to indimail database. You must use the mysql(1) client program to change this password after installation. After changing the password you have to edit /etc/indimail/control/host.mysql (on FreeBSD/Darwin /usr/local/etc/indimail/control/host.mysql)
2. Creates MySQL user 'mysql' with 'password 4-57343-'. This user has all MySQL privileges. You must use the mysql(1) client program to change this password after installation.
3. Creates MySQL user 'admin' with password 'benhur20'. This user has shutdown privilege in MySQL. You must use the mysql(1) client program to change this password after installation. After changing the password edit the file /service/mysql.3306/shutdown (/usr/local/etc/indimail/sv/mysql.3306/shutown on FreeBSD/Darwin).
4. Creates MySQL user 'repl' with password 'slaveserver'. This user has privilege to replicate binlogs from the master. You must use the mysql(1) client program to change this password after installation.
5. Creates user 'admin' in indimail internal database for adminclient(8). This is used by indisrvr(8) for access to various IndiMail(7) programs when indimail has been configured as a cluster/distributed domain. The password of this user is 'benhur20'. You can use mgmtpass(8) to change the password.

IMPORTANT NOTE

1. You can also set MYSQL_PASS, PRIV_PASS, ADMIN_PASS environent variables to set your own passwords before running create_services.
2. If you change the MySQL password for indimail after running create_services, edit /etc/indimail/control/host.mysql. On FreeBSD/Darwin this file will be /usr/local/etc/indimail/control/host.mysql
3. svctool requires credentials for MySQL user 'admin' for the mysqldump option. You can set credentials for privileged users in /etc/indimail/.svctool.cnf and make sure only root user has read privileges on this file. You are encouraged to read Setting MySQL Guide, on how to save MySQL credentials.

NOTE: The Darwin Mac OSX system is broken for sending emails because you can't remove /usr/sbin/sendmail. System Integrity Protection (SIP) ensures that you cannot modify anything in /bin, /sbin, /usr, /System, etc. You could disable it by using csrutil in recover mode but that is not adviseable. See this. indimail-mta requires services in /service to configure all startup items. On Mac OS X, it uses `/etc/synthetic.conf' to create a virtual symlink of /service to /usr/local/etc/indimail/sv. This file is created/modified by 'svctool --add-boot' command. For program that need to send mails, you will need to call /usr/local/bin/sendmail (indimal-mta's sendmail replacement). The OS and all utilites like cron, mailx, etc will continue to use /usr/sbin/sendmail. There is nothing you can do about it, other than fooling around with SIP.

Enable svscan to be started at boot

$ sudo /usr/sbin/svctool --config=add-boot

You can enable indimail-mta as an alternative mta (if your system supports the alternatives commaand)

$ sudo  /usr/bin/svctool --config=add-alt

You can remove automatic startup at boot by running the command

$ sudo /usr/sbin/svctool --config=rm-boot

Start Services

indimail, indimail-mta uses systemd.unit file to load all indimail services. This is the standard unit file that gets installed as /lib/systemd/system/svscan.service

[Unit]
Description=SVscan Service
After=local-fs.target network.target

[Service]
ExecStart=/usr/libexec/indimail/svscanboot /service
ExecStop=/etc/init.d/svscan stop
Restart=on-failure
Type=simple
PrivateTmp=yes

[Install]
Alias=indimail.service
Alias=indimail-mta.service
WantedBy=multi-user.target

You can override values by creating a file override.conf in /lib/systemd/system/svscan.service.d. As an example, on a raspberry pi system, you should have svscan started only after the system clock is synchronized with a NTP source (many SBC don't have battery backed Real Time Clock - RTC). This ensures that svscan gets started when the system has a correct date, time so that logs created will not have absurd timestamps.

[Unit]
Wants=time-sync.target
After=local-fs.target remote-fs.target time-sync.target network.target network-online.target systemd-networkd-wait-online.service

So if you have a system without a battery backed RTC, you should do this (even when you do a binary installation)

$ sudo mkdir /lib/systemd/system/svscan.service.d
$ sudo cp /usr/share/indimail/boot/systemd.override.conf /lib/systemd/system/svscan.service.d/override.conf
$ sudo systemctl daemon-reload

Now you can start the indimail/indimail-mta service

$ sudo systemctl start svscan # Linux
or
$ sudo service svscan start # Linux/FreeBSD
or
$ /etc/init.d/svscan start # Linux
or
$ sudo launchctl start org.indimail.svscan # Mac OSX
or
$ qmailctl start # Universal

After starting svscan as given above, your system will be ready to send and receive mails, provided you have set your system hostname, domain name IP addresses and setup mail exchanger in DNS. You can look at this guide to do that.

Check Status of Services

The svstat command can be used to query the status of various services. You can query for all services like below. You can query the status of a single service like running a command like this.

% sudo svstat /service/qmail-smtpd.25

The argument to svstat should be a directory in /service. Each directory in /service refers to an indimail-mta/indimail service. e.g. /service/qmail-smtpd.25 refers to the SMTP service serving port 25.

If you don't have /service create a link to /etc/indimail/sv (/usr/local/etc/indimail/sv on FreeBSD/Darwin). I'm working on creating this link automatically during setup.

Create Virtual Domains

The commands below will look familiar to you if you have used vpopmail. IndiMail-virtualdomains has many commands with the same name but is a totally new package with all code written in djb style. Also the feature list is extensive compated to vpopmail. But unlike vpopmail, indimail-virtualdomains supports MySQL database only. The idea for doing indimail-virtualdomains comes from looking at how vpopmail works (See #History). You can extend what many of indimail-virtualdomains programs by creating a script with the same name in /usr/libexec/indimail. These scripts will be passed the same arguments that you pass the original programs. The man pages for the commands will have more details.

STEP 1

Add a virtual domain

For this example, we will add a domain "indimail.org"

For a non-clustered domain you would execute the following command

% sudo /usr/bin/vadddomain indimail.org
    or
% sudo /usr/bin/vadddomain indimail.org password-for-postmaster

For a clustered domain you would execute the following command

% sudo /usr/bin/vadddomain -D indimail -S localhost \
    -U indimail -P ssh-1.5- -p 3306 -c indimail.org password-for-postmaster
    or
% sudo /usr/bin/vadddomain -D indimail -S localhost \
    -U indimail -P ssh-1.5- -p 3306 -c indimail.org password-for-postmaster

vadddomain will modify the following qmail files (default locations used) /etc/indimail/control/locals /etc/indimail/control/rcpthosts /etc/indimail/control/morercpthosts (if rcpthosts > than 50 lines) /etc/indimail/control/virtualdomains /etc/indimail/users/assign /etc/indimail/users/cdb

NOTE: FreeBSD/Darwin has /usr/local/etc/indimail instead of /etc/indimail

It will also create a domains directory ~indimail/domains/indimail.org and user's home directory and Maildir ~indimail/domains/indimail.org/postmaster/Maildir

If you do not specify a password on the command line, it will prompt for a password for the postmaster.

Then it will send a kill -HUP signal to qmail-send telling it to re-read the control files.

Note: setting up DNS MX records for the virtual domain is not covered in this INSTALL file. You can look at this guide to do that.

STEP 2

Add a new user.

You can use vadduser to add users.

% sudo /usr/bin/vadduser [email protected]
    or
% sudo /usr/bin/vadduser [email protected] <password-for-newuser>

STEP 3

Delete a user

% sudo /usr/bin/vdeluser [email protected] (for the indimail.org virtualdomain example)

STEP 4

Delete a virtual domain

% sudo /usr/bin/vdeldomain indimail.org

STEP 5

Changing a users password

% sudo /usr/bin/vpasswd [email protected]
        or
% sudo /usr/bin/vpasswd [email protected] <[email protected]>

STEP 6

Man pages

A lot of the underlying indimail details are not covered in this file. This is on purpose. If you want to find out the internal workings of indimail and qmail look into all files in /usr/share/indimail/doc and /usr/share/man/man?

As a first step, do

% man indimail

Send / Receive Mails

At this stage, your setup is ready to send mails to the outside world. To receive mails, you need to create your actual domain (instead of example.com) using vadddomain and setup a mail exchanger record for your domain (MX record). To send mails, you can either use SMTP or use sendmail (which is actually /usr/bin/sendmail). You can do the following to send a test mail. The mail command is part of the BSD mail/mailx package

% ( echo 'First M. Last'; uname -a) | mail -s "IndiMail Installation" [email protected]

You can also play around with the system at this point. Try POP3 (110), POP3s (995), IMAP (143), IMAPs (993), SMTP (25), SMTPS (465), Submission (587). You can use telnet or nc command to connect to these ports. You could also configure your mail client to connect to this ports and set it up for regular mail usage.

Replace First M. Last with your name.

Create Local Binary Packages

If you need to have indimail on multiple machines, you can build binary packages once and install the same package on multiple machines. The other big advantage of using a binary build is that the binary installation will give you fully functional, configured system using your hostname for defaults. You can always change these configuration files in /etc/indimail to cater to your requirements later. With a binary build, you don't need to run the create_services command. To generate RPM packages locally for all components refer to Binary Packages.

You can also download pre-built binary packages from openSUSE Build Service, described in the chapter Binary Builds on OBS.

NOTE: binary package for FreeBSD and OSX is in my TODO list and I need help to figure this out.

Binary Builds on openSUSE Build Service and Copr

Build Status on Open Build Service

Build Status on copr

You can get binary RPM / Debian packages at

• Stable Releases
• Experimental Releases
• copr Releases

If you want to use DNF / YUM / apt-get, the corresponding install instructions for the three repositories, depending on whether you want to install a stable, an experimental or copr release, are

• Stable
• Experimental
• copr Releases. The copr repository can be enabled by running the command $ sudo dnf copr enable cprogrammer/indimail

NOTE: Once you have setup your DNF / YUM / apt-get repo, you an also decide to install the additional software

1. indimail-access - IMAP/POP3 & fetchmail for mail retreival
2. indimail-auth (nssd - providing Name Service Switch and pam-multi providing multiple PAM modules for flexible, configurable authentication methods)
3. indimail-spamfilter - SPAM filter capabillity using bogofilter - https://bogofilter.sourceforge.io

Docker / Podman Containers

The docker repository can be used to pull docker/podman images for indimail/indimail-mta

For latest details refer to README

Earlier I used to provide docker / podman container images on docker hub. But recently (Jul 25, 2021) docker, without any warning or communication, on the sly, has removed the ability to connect with a github account unless you pay them dollars every month - a questionable business practice. As a principle, I no longer support docker. I have deleted all container images that were hosted there. Instead of the Docker Container Registry, I now use the Github Container Registry. You can also build your own images. Refer to README on how to build your own container images. If you cannot build it on your own, ping me and I will be happy to build it for you.

History

Both indimail-mta and indimail-virtualdomains started in late 1999 as a combined package of unmodified qmail and modified vpopmail.

indimail-mta started as a unmodified qmail-1.03. This was when I was employed by an ISP in late 1999. The ISP was using Critical Path's ISOCOR for providing Free and Paid email service. Then the dot com burst happened and ISP didn't have money to spend on upgrading the Sun Enterprise servers. The mandate was to move to an OSS/FS solution. After evaluating sendmail, postfix and qmail, we chose qmail. During production deployment, qmail couldn't scale on these servers. The issue was the queue's todo count kept on increasing. We applied the qmail-todo patch, but still we couldn't handle the incoming email rate. By now the customers were screaming, the corporate users were shooting out nasty emails. We tried a small hack the solved this problem. Compiled 20 different qmail setups, with conf-qmail as /var/qmail1, /var/qmail2, etc. Run qmail-send for each of these instance. A small shim was written which would get the current time and divide by 20. The remainder was used to do exec of /var/qmail1/bin/qmail-queue, /var/qmail2/bin/qmail-queue, etc. The shim was copied as /var/qmail/bin/qmail-queue. The IO problem got solved. But the problem with this solution was compiling the qmail source 20 times and copying the shim as qmail-queue. You couldn't compile qmail on one machine and use the backup of binaries on another machine. Things like uid, gid, the paths were all hardcoded in the source. That is how the base of indimail-mta took form by removing each and every hard coded uids, gids and paths. indimail-mta still does the same thing that was done in the year 2000. The installation creates multiple queues - /var/indimail/queue/queue1, /var/indimail/queue/queue2, etc. A new daemon named qmail-daemon uses QUEUE_COUNT env variable to run multiple qmail-send instances. Each qmail-send instance can instruct qmail-queue to deposit mail in any of the queues installed. All programs use qmail-multi, a qmail-queue frontend to load balance the incoming email across multiple queues.

indimail-virtualdomain started with a modified vpopmail base that could handle a distributed setup - Same domain on multiple servers. Having this kind of setup made the control file smtproutes unviable. email would arrive at a relay server for user@domain. But the domain '@domain' was preset on multiple hosts, with each host having it's own set of users. This required special routing and modification of qmail (especially qmail-remote) to route the traffic to the correct host. vdelivermail to had to be written to deliver email for a local domain to a remote host, in case the user wasn't present on the current host. New MySQL tables were created to store the host information for a user. This table would be used by qmail-local, qmail-remote, vdelivermail to route the mail to the write host. All this complicated stuff had to be done because the ISP where I worked, had no money to buy/upgrade costly servers to cater to users, who were multiplying at an exponential rate. The govt had just opened the license for providing internet services to private players. These were Indians who were tasting internet and free email for the first time. So the solution we decided was to buy multiple intel servers Compaq Proliant running Linux and make the qmail/vpopmail solution horizontally scalable. This was the origin of indimail-1.x which borrowed code from vpopmail, modified it for a domain on multiple hosts. indimail-2.x was a complete rewrite using djb style, using libqmail as the standard library for all basic operations. All functions were discarded because they used the standard C library. The problem with indimail-2.x was linking with MySQL libraries, which caused significant issues building binary packages on openSUSE build service. Binaries got built with MySQL/MariaDB libraries pulled by OBS, but when installed on a target machine, the user would have a completely different MySQL/MariaDB setup. Hence a decision was taken to load the library at runtime using dlopen/dlsym. This was the start of indimail-3.x. The source was moved from sourceforge.net to github and the project renamed as indimail-virtualdomains from the original name IndiMail. The modified source code of qmail was moved to github as indimail-mta.
