GitHub - mazelab/docker-haraka-dovecot: Mailserver with Haraka, Dovecot and MySQL

Mailserver with Haraka, Dovecot and MySQL

Haraka SMTP Email Server with Dovecot and MySQL backend. This container includes services for SMTP, POP3 and IMAP.

Please note that this is a highly experimental build.

features:

Quota tracking
Spam filtering
MD5-Crypt authentication
Forwarder (alias) support

Requirement

MySQL Server

Installation

docker pull mazelab/haraka-dovecot:latest

Quick Start

Start a `mysql` instance

Skip if you want to use your own mysql server.

docker run -d --name mysql-mail -e MYSQL_ROOT_PASSWORD=my-secret-pw -e MYSQL_DATABASE=mail-sample mysql

Start a `mail` server instance:

If you use your own mysql server you have to set the environment variables accordingly.

docker run -d -v /home/mail/dirs/:/data/ -p 25:25 -p 110:110 -p 143:143 -e HOSTNAME=mail.dev --link mysql-mail:mysql -e MYSQL_HOST=mysql -e MYSQL_PORT=3306 -e MYSQL_USER=root -e MYSQL_PASS=my-secret-pw -e MYSQL_DATABASE=mail-sample --name mail-sample mazelab/haraka-dovecot

File Permissions

Currently the mounted email dir must have the uid 8 which ist the standard mail user. So if you mounted into /data you have to set the permissions accordingly. Otherwise haraka will fail on local delivery and stop.

# either
chown -R mail: /home/mail
# or
chown -R 8:8 /home/mail

Setup database

To actually use the mail server you have to initialize the database.

Import the database structure.

If you used the above mysql container then do:

docker exec -it mysql-mail mysql -u root -pmy-secret-pw mail-sample

Then copy/paste the dump and close the shell with exit

Add Domain

Haraka needs to know which domains are acceptable. Only email from these domains will be delivered.

docker exec -it mail-sample sh -c 'echo "test.dev" >> /srv/haraka/config/host_list'

Add User

Get the password first:

docker exec mail-sample doveadm pw -s MD5-CRYPT -p thepassword
{MD5-CRYPT}$1$DpBbHS.2$vHGFpWG4V0aR24JpkiusC/ -> password string is $1$DpBbHS.2$vHGFpWG4V0aR24JpkiusC/

Go into mysql again:

docker exec -it mysql-mail mysql -u root -pmy-secret-pw mail-sample

Use query to add new users:

// email [email protected], pw: thepassword, 100 MB quota
INSERT INTO `users` (name, password, domain, uid, gid, gecos, home, quota) VALUES('test','$1$DpBbHS.2$vHGFpWG4V0aR24JpkiusC/','test.dev',1,0,'this is just a test','/data/test.dev/test','100');

// email [email protected], pw: thepassword, 1 MB quota
INSERT INTO `users` (name, password, domain, uid, gid, gecos, home, quota) VALUES('testquota','$1$DpBbHS.2$vHGFpWG4V0aR24JpkiusC/','test.dev',1,0,'this is just a quota test','/data/test.dev/quota','1');

Data Store

Account data is stored in MySQL.

Maildir

mailbox : All mailboxes are stored in a volume at /data/

Database

users: Contains the user info. e.g. login, maildir path, quota ...

quota : Contains the used mailbox size (dovecot will update this table automatically)

forwarder : Contains the rules of forwarder (aliases)

Other

Quota

Dovecot keeps track of the current quota usage. MySQL is used to store the quota.

SpamAssassin

E-mail spam filtering based on content-matching rules.

Ports

SMTP: 25
IMAP: 143 or 993 (SSL/TLS)
POP3: 110 or 995 (SSL/TLS)

Database Design

The SQL queries are defined in config files and used by Haraka and Dovecot. When changing the tables you must modify the following SQL queries in:

/etc/dovecot/dovecot-sql.conf.ext
/srv/haraka/config/aliases_mysql.ini
/srv/haraka/config/auth_sql_cryptmd5.ini
/srv/haraka/config/quota.check.ini

Create Tables

Create the tables like this:

CREATE TABLE `users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(32) NOT NULL,
  `password` varchar(255) NOT NULL,
  `domain` varchar(255) NOT NULL,
  `uid` int(11) DEFAULT NULL,
  `gid` int(11) DEFAULT NULL,
  `gecos` varchar(255) DEFAULT NULL,
  `home` varchar(255) NOT NULL,
  `quota` varchar(255) DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB;

CREATE TABLE `forwarder` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `address` varchar(128) NOT NULL,
  `action` varchar(8) NOT NULL,
  `aliases` text DEFAULT '',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB;

CREATE TABLE `quota` (
  `username` varchar(255) NOT NULL,
  `bytes` bigint(20) NOT NULL DEFAULT '0',
  `messages` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`username`)
) ENGINE=InnoDB;

Example datasets

Table `quota`:

username	bytes	messages
foo@qux	1214	2
bar@qux	0	0

Table `forwarder`:

id	address	action	aliases
1	foo@qux	drop
2	bar@qux	alias	foo@bar \| foo@qux

Table `users`:

id	name	password	domain	uid	gid	gecos	home	quota
1	baz	$1$x5b..	qux	8	8	baz	/data/qux/baz	2

SSL configuration

The placement of files enables the use of SSL/TLS (and STARTTLS).

Certificate Location

Use /tls/ volume to mount a directory inside the container with the key files.

/tls/tls_key.pem
/tls/tls_cert.pem

Password protected key files

SSL key files may be password protected. Use the SSL_KEY_PASSWORD environment variable on Docker to provide the password.

Running the Mailserver

To create a new mail server for your domain you should use the following commands:

docker run -v /home/mail/dirs/:/data/
    -p 25:25 -p 110:110 -p 143:143
    -e HOSTNAME=yourdomain.com
    -e MYSQL_HOST=sql.yourdomain.com
    -e MYSQL_PORT=3306
    -e MYSQL_USER=username
    -e MYSQL_PASS=password
    -e MYSQL_DATABASE=mail
    --name mailserver mazelab/haraka-dovecot

Now you can access port 25, 110 and 143.

Environment variables

MYSQL_HOST: Server address of the MySQL server to use
MYSQL_USER: Username to authenticate with
MYSQL_PASS: Password of the MySQL user
MYSQL_DATABASE: Database name to use
HOSTNAME: Server hostname for the container
SSL_KEY_PASSWORD: Password for protected SSL key files
