Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.10)

Version 1.0

This tutorial is Copyright (c) 2008 by Falko Timme. It is derived from a tutorial from Christoph Haas which you can find at http://workaround.org. You are free to use this tutorial under the Creative Commons license 2.5 or any later version.

This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses.

The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

The advantage of such a "virtual" setup (virtual users and domains in a MySQL database) is that it is far more performant than a setup that is based on "real" system users. With this virtual setup your mail server can handle thousands of domains and users. Besides, it is easier to administrate because you only have to deal with the MySQL database when you add new users/domains or edit existing ones. No more postmap commands to create db files, no more reloading of Postfix, etc. For the administration of the MySQL database you can use web based tools like phpMyAdmin which will also be installed in this howto. The third advantage is that users have an email address as user name (instead of a user name + an email address) which is easier to understand and keep in mind.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.

This document comes without warranty of any kind! I want to say that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

 

1 Preliminary Note

This tutorial is based on Ubuntu 8.10 Server (Intrepid Ibex), so you should set up a basic Ubuntu 8.10 server installation before you continue with this tutorial (e.g. as shown on the pages 1 - 3 in this tutorial: The Perfect Server - Ubuntu Intrepid Ibex (Ubuntu 8.10)). The system should have a static IP address. I use 192.168.0.100 as my IP address in this tutorial and server1.example.com as the hostname.

Make sure that you are logged in as root (type in

sudo su

to become root), because we must run all the steps from this tutorial as root user.

It is very important that you make /bin/sh a symlink to /bin/bash...

ln -sf /bin/bash /bin/sh

... and that you disable AppArmor:

/etc/init.d/apparmor stop
update-rc.d -f apparmor remove
apt-get remove apparmor apparmor-utils

 

2 Install Postfix, Courier, Saslauthd, MySQL, phpMyAdmin

To install Postfix, Courier, Saslauthd, MySQL, and phpMyAdmin, we simply run

apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server courier-authdaemon courier-authlib-mysql courier-pop courier-pop-ssl courier-imap courier-imap-ssl postfix-tls libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl phpmyadmin apache2 libapache2-mod-php5 php5 php5-mysql libpam-smbpass

You will be asked a few questions:

New password for the MySQL "root" user: <-- yourrootsqlpassword
Repeat password for the MySQL "root" user: <-- yourrootsqlpassword
Create directories for web-based administration? <-- No
General type of mail configuration: <-- Internet Site
System mail name: <-- server1.example.com
SSL certificate required <-- Ok
Web server to reconfigure automatically: <-- apache2

 

3 Apply The Quota Patch To Postfix

We have to get the Postfix sources, patch it with the quota patch, build new Postfix .deb packages and install those .deb packages:

apt-get install build-essential dpkg-dev fakeroot debhelper libgdbm-dev libldap2-dev libpcre3-dev libssl-dev libsasl2-dev postgresql-server-dev-8.3 po-debconf dpatch libmysqlclient15-dev lsb-release libcdb-dev libdb-dev hardening-wrapper

cd /usr/src
apt-get source postfix

(Make sure you use the correct Postfix version in the following commands. I have Postfix 2.5.5 installed. You can find out your Postfix version by running

postconf -d | grep mail_version

The output should look like this:

root@server1:/usr/src# postconf -d | grep mail_version
mail_version = 2.5.5
milter_macro_v = $mail_name $mail_version
root@server1:/usr/src#

)

wget http://vda.sourceforge.net/VDA/postfix-2.5.5-vda-ng.patch.gz
gunzip postfix-2.5.5-vda-ng.patch.gz
cd postfix-2.5.5
patch -p1 < ../postfix-2.5.5-vda-ng.patch
dpkg-buildpackage

You might see a warning like this at the end of the dpkg-buildpackage command:

dpkg-buildpackage: warning: Failed to sign .dsc and .changes file

You can ignore this message.

Now we go one directory up, that's where the new .deb packages have been created:

cd ..

The command

ls -l

shows you the available packages:

root@server1:/usr/src# ls -l
total 5872

root@server1:/usr/src#

Pick the postfix and postfix-mysql packages and install them like this:

dpkg -i postfix_2.5.5-1_i386.deb postfix-mysql_2.5.5-1_i386.deb

 

4 Create The MySQL Database For Postfix/Courier

Now we create a database called mail:

mysqladmin -u root -p create mail

Next, we go to the MySQL shell:

mysql -u root -p

On the MySQL shell, we create the user mail_admin with the passwort mail_admin_password (replace it with your own password) who has SELECT,INSERT,UPDATE,DELETE privileges on the mail database. This user will be used by Postfix and Courier to connect to the mail database:

GRANT SELECT, INSERT, UPDATE, DELETE ON mail.* TO 'mail_admin'@'localhost' IDENTIFIED BY 'mail_admin_password';
GRANT SELECT, INSERT, UPDATE, DELETE ON mail.* TO 'mail_admin'@'localhost.localdomain' IDENTIFIED BY 'mail_admin_password';
FLUSH PRIVILEGES;

Still on the MySQL shell, we create the tables needed by Postfix and Courier:

USE mail;

CREATE TABLE domains (
domain varchar(50) NOT NULL,
PRIMARY KEY (domain) )
TYPE=MyISAM;

CREATE TABLE forwardings (
source varchar(80) NOT NULL,
destination TEXT NOT NULL,
PRIMARY KEY (source) )
TYPE=MyISAM;

CREATE TABLE users (
email varchar(80) NOT NULL,
password varchar(20) NOT NULL,
quota INT(10) DEFAULT '10485760',
PRIMARY KEY (email)
) TYPE=MyISAM;

CREATE TABLE transport (
domain varchar(128) NOT NULL default '',
transport varchar(128) NOT NULL default '',
UNIQUE KEY domain (domain)
) TYPE=MyISAM;

quit;

As you may have noticed, with the quit; command we have left the MySQL shell and are back on the Linux shell.

The domains table will store each virtual domain that Postfix should receive emails for (e.g. example.com).

domain
example.com

The forwardings table is for aliasing one email address to another, e.g. forward emails for info@example.com to sales@example.com.

source destination
info@example.com sales@example.com

The users table stores all virtual users (i.e. email addresses, because the email address and user name is the same) and passwords (in encrypted form!) and a quota value for each mail box (in this example the default value is 10485760 bytes which means 10MB).

email password quota
sales@example.com No9.E4skNvGa. ("secret" in encrypted form) 10485760

The transport table is optional, it is for advanced users. It allows to forward mails for single users, whole domains or all mails to another server. For example,

domain transport
example.com smtp:[1.2.3.4]

would forward all emails for example.com via the smtp protocol to the server with the IP address 1.2.3.4 (the square brackets [] mean "do not make a lookup of the MX DNS record" (which makes sense for IP addresses...). If you use a fully qualified domain name (FQDN) instead you would not use the square brackets.).

BTW, (I'm assuming that the IP address of your mail server system is 192.168.0.100) you can access phpMyAdmin over http://192.168.0.100/phpmyadmin/ in a browser and log in as mail_admin. Then you can have a look at the database. Later on you can use phpMyAdmin to administrate your mail server.

help my please

What a great guide!

I found a small typo in the configuration of postfix.

The line:

postconf -e 'virtual_mailbox_extended = yes'

should be:

postconf -e 'virtual_maildir_extended = yes'

If not, quota does not work

Best regards,

Hans Audun

From: Gergely Kiss at: 2009-01-11 21:55:52

This howto is great, works as expected, however I've found a small issue with it: quota warnings don't get sent until the setting "virtual_maildir_extended = yes" is added  to the main postfix config file (/etc/postfix/main.cf). This instructs postfix to create or update the maildirsize file for each maildir, which is required to check the actual size of a maildir.

Guys,

for the quota set.I am not able to download the quota.txt from http://puuhis.net/vhcs/quota.txt.

It would be great If you can tell me where I can download the same

 Hello

 I got the same problem I dont know that much from this system and are very fresh to it

I also got this error  `pure-ftpd-mysql' uses 32-bit capabilities (legacy support in use)

means (mysql is stoping) if its in your case the same then you have to fix this problem first

I am still doing resource on it to solve it , if I did fix it I will let you know

Regards FJB

Hi, my problem was the same, courier couldn't find mail directory (in my case it is /home/vmail). Problem is in /etc/courier/authmysqlrc  line: MYSQL_MAILDIR_FIELD CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/')

I just changed highlighted part to '/home/vmail' and now at least I can login using squirrel mail.

 I still don't know why courier can't login server.example.com/vmail. I would appreciate if someone who understands this issue could explain it.

From: Anonymous at: 2009-02-11 10:07:39

I had a similar issue when the change password plugin was loaded. Login and all I got was a blank page. Unloaded the plugin and it worked ok.

 It ended up being a stray bit of code in the sqlpass change config.php

Make sure you don't have any stray bits of code. I had "                        );" just under the $password_update_queries section.

From: dleonce at: 2009-01-08 08:43:07

I am having the same problem.  During the setup, I inadvertently selected YES to the question "Create directories for web-based administration?" in STEP 2.To install Postfix, Courier, Saslauthd, MySQL, and phpMyAdmin. Can someone tell me the implications of this? Could this be the reason for this error and can someone assist with the configuration changes?

From: LQman at: 2009-01-11 11:48:50

This is my opinion about connection dropped by imap.

 Imap try to open user directory (maildir), while the directory (maildir) doesn't exist or didn't created before.

So we have to send "welcome message" to every new user, than courier will make maildir automatically, after that our new user will be able to login.

From: justin at: 2009-03-05 16:18:45

where does it create the maildir directory ?  can i just run the makemaildir command to create it manually ?

From: Lochinvar at: 2008-12-30 04:52:01

I had the same issue. I solved it by sending an email to the account in question.

What is going on is that the directory to contain the email has yet to be created and the server throws the error.

 Try using mailx to send a sample email to the account.

From: keddie at: 2008-12-25 23:52:35

Try this:

 run squirrelmail-configure command, then go to server settings (2), next go to update IMAP settings (A), change IMAP Port(5) to 993 and Secure IMAP (TLS)(7) to true.

Hope that will help :)

From: at: 2008-12-26 13:46:44

I did it. Nothing has changed.

From: Black-Adder at: 2009-01-18 16:38:07

Hello i have solved the problem. in the place of mail_user a put in the mysql user vmail that i maked with phpmyadmin and gif the richts to db mail after that it works

From: TomT at: 2009-01-18 19:44:03

Solved my own problem...  Whilst edditing one of the files I pasted an extra : at the end of the line.
That's what stopped the sending of emails :(

SquirrelMail was giving me a blank page, becuase I'd missed entering my MySQL password in one of the files for the password_changer plugin.

All my own fault :)

So how do I tell if ClamAV is upto date ?? And that SpamAssasin is working properly ?
I don't see any ref to Clamav in the email headers. Is that normal ?

Is it possible to set up more DNSBL or RBL entries in either Postfix or SpamAssasin ?
Is it possible to drop connections from any hosts that don't haev a FQN ? with exceptions based on host names ??
 

Thanks :)

I have a problem where it is not letting me log as well. I look at /var/log/mail.log and this is what I see. I have tried looking through all the config files and I cannot find why it is sending UNKNOWN_USER instead of mail_admin
and advise would be great. Thank you all in advance.

Any hints?

From: Anonymous at: 2009-01-18 16:20:33

I've followed this guide and installed everything as shown.

When I go to my browser and view http://192.168.1.172/squirrelmail I get the log in screen.

I log in and nothing. No pages showing waiting mail. I have telnetted in and using STAT I can see mail waiting.  Any ideas what's wrong with SquirrelMail ??

Also when I try to send I get asked for a password, I've entered the same pasword that I used for IMAP/POP3 but it won't let me send.

Any Ideas ?

Thanks
