Summary

This tutorial is written for:

Red Hat Enterprise Linux 5.x, 6.x
CentOS 5.x, 6.x
Scientific Linux 6.x

This tutorial describes how to integrate DBMail in iRedMail, store mail messages in MySQL.

What DBMail is? DBMail is an open-source project that enables storage of mail messages in a relational database. Currently MySQL, PostgreSQL and SQLite can be used as storage backends. Web site: http://www.dbmail.org/
Why DBMail? Quote from DBMail web site:
- Scalability. DBMail is as scalable as the database system used for storage.
- Manageability. DBMail can be managed by updating the relational database or directory service - without shell access.
- Speed. Dbmail uses very efficient, database specific queries for retrieving mail information.
- Security. Dbmail doesn't require filesystem access. It's as secure as the database and directory server used.
- Flexibility. Changes in a Dbmail system (adding of users, changing passwords etc.) are effective immediately. Users can be stored in the database, or managed separately in an LDAP server such as OpenLDAP or Active Directory.

Note:

For RHEL/CentOS/Scientific Linux 5.x, we will install DBMail-2.2.17 from yum repository EPEL.
For RHEL/CentOS/Scientific Linux 6.x, we will install DBMail-3.0.0-rc from yum repository EPEL.
DBMail-2.x doesn't provide native TLS/SSL support.

Requirements and Preparations

OS:
- Red Hat Enterprise Linux 5.x or 6.x
- CentOS 5.x or 6.x
- Scientific Linux 5.x or 6.x
A running iRedMail server. MySQL server is installed by default in both OpenLDAP and MySQL backends, so either backend is OK. If you don't have a running iRedMail server, please follow its installation guide here: http://www.iredmail.org/doc.html
DBMail version:
- 3.0.0 serial: 3.0.0-rc2 or later versions. There's a compatibility issue in DBMail-3.0.0-rc1, it won't work with Cyrus-SASL for SMTP AUTH.
- 2.2.x.

DBMail, IMAP/POP3 Server

Preparations

Before installing DBMail software, we need to create necessary system user and group to run DBMail daemons, and create necessary MySQL database which used to store mail accounts and messages.

Create necessary system user (dbmail) and group (dbmail).

Terminal:

# useradd -s /sbin/nologin -m dbmail

Above command will create group dbmail and system user dbmail. You can verify it with command id:

Terminal:

# id dbmail
uid=504(dbmail) gid=504(dbmail) groups=504(dbmail)

Create necessary MySQL database to store mail accounts and mails: dbmail. Replace password_of_dbmail below with your password.

Terminal:

$ mysql -uroot -p
mysql> CREATE DATABASE dbmail DEFAULT CHARACTER SET utf8;
mysql> GRANT ALL ON dbmail.* TO dbmail@localhost IDENTIFIED BY 'password_of_dbmail';
mysql> FLUSH PRIVILEGES;

We now have a MySQL database dbmail, you can access it with MySQL user dbmail and password password_of_dbmail. You can verify it with MySQL command line:

Terminal:

$ mysql -udbmail -p
Enter password:                # <- Type password of MySQL user dbmail here.

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| dbmail             |      # <- Database 'dbmail' is available.
+--------------------+
2 rows in set (0.04 sec)

mysql>

Stop Dovecot daemon. Since Dovecot will be replaced by DBMail, we must stop it:

Terminal:

# /etc/init.d/dovecot stop
# chkconfig --level 345 dovecot off

Install DBMail

DBMail is available in EPEL repository, we will use this yum repository to install DBMail.

It's now ready to install DBMail core component and library used to connect MySQL.

Terminal:

#
# ---- For RHEL/CentOS/Scientific Linux 5.x ----
#
# rpm -ivh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
# yum clean all
# yum install dbmail dbmail-mysql

#
# ---- For RHEL/CentOS/Scientific Linux 6.x ----
#
# rpm -ivh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
# yum clean all
# yum install dbmail

On RHEL/CentOS/Scientific Linux 6.x, please make sure you have DBMail 3.0.0-rc3 or later version installed:

Terminal:

# rpm -q dbmail
dbmail-3.0.0-0.6.rc3.el6.x86_64

Main configure file of DBMail is /etc/dbmail.conf by default, we will configure it later.

DBMail provides a MySQL template file /usr/share/doc/dbmail-x.y.z/sql/mysql/create_tables.mysql (replace 'x.y.z' by real version number on your server), we should import it to create necessary MySQL tables to store mail accounts and messages. Here we use 'dbmail-3.0.0' for example.

Terminal:

# rpm -ql dbmail | grep 'create_tables.mysql'
/usr/share/doc/dbmail-3.0.0/sql/mysql/create_tables.mysql

# mysql -udbmail -p
mysql> USE dbmail;
mysql> SOURCE /usr/share/doc/dbmail-3.0.0/sql/mysql/create_tables.mysql;
mysql> SHOW TABLES;               # < See what tables were created.

Configure DBMail

Now open configure file of DBMail, /etc/dbmail.conf, update below settings:

File: /etc/dbmail.conf

[DBMAIL]

Create directory to store PID files:

Terminal:

# mkdir /var/run/dbmail
# chown dbmail:dbmail /var/run/dbmail

It's ready to start DBMail daemons:

Terminal:

# for i in dbmail-imapd dbmail-lmtpd dbmail-pop3d dbmail-timsieved; do /etc/init.d/$i restart; done

Make sure DBMail daemons will start when system startup:

Terminal:

# for i in dbmail-imapd dbmail-lmtpd dbmail-pop3d dbmail-timsieved; do chkconfig --level 345 $i on; done

Check status of DBMail daemons:

Terminal:

# netstat -ntlp | grep dbmail
tcp        0      0 0.0.0.0:110                 0.0.0.0:*                   LISTEN      1747/dbmail-pop3d

Create testing account

DBMail daemons are running, let's create a testing account to test POP3/POP3S/IMAP/IMAPS/Managesieve services.

Create a testing account test@domain.ltd, with password mypass:

Terminal:

# dbmail-users -p md5 -a test@domain.ltd -w mypass -s test@domain.ltd
Adding INBOX for new user... ok.
[test@domain.ltd]
Done
test@domain.ltd:x:5:0:0.00:0.00:test@domain.ltd

Refer to DBMail wiki site for more information about managing users: http://dbmail.org/dokuwiki/doku.php/manage_users

Test POP3/IMAP/Managesieve services with telnet

It's OK to test POP3/POP3S/IMAP/IMAPS services with telnet, mutt or Roundcube webmail, here we use telnet and mutt instead. After testing, you can login to Roundcube Webmail directly.

Testing POP3 service

Terminal:

$ telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
+OK DBMAIL pop3 server ready to rock <e2ef9332465296ebd4ec7ae5828d9cc3@c60.iredmail.org>   # <-- DBMail response

USER test@domain.ltd                # <- Type this command to login
+OK Password required for test@domain.ltd

PASS mypass                      # <-- Type your password
+OK test@domain.ltd has 0 messages (0 octets)

LIST                   # <-- Check mailbox.
+OK 0 messages (0 octets)
.

QUIT                 # <-- DIsconnect
+OK see ya later
Connection closed by foreign host.

Telnet doesn't support SSL service, so we test POP3S with mutt instead.

Terminal:

$ mutt -f pops://"test@domain.ltd":mypass@localhost

If POP3S works well, mutt will show you an empty mailbox. Then type 'q' to exit mutt.

Testing IMAP service

Terminal:

$ telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 AUTH=LOGIN AUTH=CRAM-MD5 STARTTLS ID] dbmail 3.0.0-rc1 ready.       # <-- DBMail response.

. LOGIN test@domain.ltd mypass                # <-- Login. Don't forget the leading dot in command.
* CAPABILITY IMAP4rev1 STARTTLS ID ACL RIGHTS=texk NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE
. OK LOGIN completed

. LIST '' '*'                  # <-- Check mailbox.
* LIST (\hasnochildren) "/" "INBOX"
. OK LIST completed

. LOGOUT               # <-- Disconnect.
* BYE
. OK LOGOUT completed
Connection closed by foreign host.

Telnet doesn't support SSL service, so we test IMAPS with mutt instead.

Terminal:

$ mutt -f imaps://"test@domain.ltd":mypass@localhost

If IMAPS works well, mutt will show you an empty mailbox. Then type 'q' to exit mutt.

Testing Managesieve service

Before testing managesieve service, we have to encode username and password first.

Download a small perl script here: http://www.rename-it.nl/dovecot/utilities/sieve-auth-command.pl
Run this script to encode your username and password:

Terminal:

$ perl sieve-auth-command.pl test@domain.ltd mypass
AUTHENTICATE "PLAIN" "AHRlc3RAZG9tYWluLmx0ZABteXBhc3M="

The command output is what we need.

Now start to test managesieve service:

Terminal:

$ telnet localhost 4190
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
"IMPLEMENTATION" "DBMail timsieved 3.0.0-rc1"
"SASL" "PLAIN"
"SIEVE" "regex imap4flags relational subaddress fileinto reject envelope vacation notify "
OK


AUTHENTICATE "PLAIN" "AHRlc3RAZG9tYWluLmx0ZABteXBhc3M="               # <-- Type this command.
OK

^]              # <-- Press Ctrl + ] to exit telnet session.
telnet> quit          # <-- Type 'quit' to quit telnet program.
Connection closed.

Integrate DBMail in Postfix

Backup Postfix config files before we go further:

Terminal:

# cp /etc/postfix/main.cf /etc/postfix/main.cf.bak
# cp /etc/postfix/master.cf /etc/postfix/master.cf.bak

Add below line in /etc/postfix/master.cf, it's new transport provided by DBMail.

File: /etc/postfix/master.cf

dbmail-lmtp     unix    -       -       n       -       -       lmtp

Since DBMail uses different SQL structure from iRedMail, we have to disable some iRedMail special features in Postfix first.

Terminal:

# postconf -e recipient_bcc_maps='' relay_domains='$mydestination' sender_bcc_maps='' transport_maps='' virtual_alias_maps=''

Update postfix setting to use DBMail transport:

Terminal:

# postconf -e virtual_transport='dbmail-lmtp:127.0.0.1:24'

Update postfix setting in /etc/postfix/main.cf, remove reject_unknown_sender_domain in smtpd_recipient_restrictions setting.

Update postfix setting to lookup mail users and aliases from DBMail MySQL database:

Terminal:

# postconf -e smtpd_sender_login_maps='proxy:mysql:/etc/postfix/dbmail_recipients.cf'
# postconf -e virtual_mailbox_domains='proxy:mysql:/etc/postfix/dbmail_domains.cf'
# postconf -e virtual_mailbox_maps='proxy:mysql:/etc/postfix/dbmail_mailboxes.cf'

Content of file /etc/postfix/dbmail_recipients.cf:

File: /etc/postfix/dbmail_recipients.cf

hosts = 127.0.0.1
dbname = dbmail
user = dbmail
password = password_of_dbmail
query = SELECT alias FROM dbmail_aliases WHERE alias='%s' LIMIT 1

Content of file /etc/postfix/dbmail_domains.cf:

File: /etc/postfix/dbmail_domains.cf

hosts = 127.0.0.1
dbname = dbmail
user = dbmail
password = password_of_dbmail
query = SELECT DISTINCT 1 FROM dbmail_aliases WHERE SUBSTRING_INDEX(alias, '@', -1) = '%s'

Content of file /etc/postfix/dbmail_mailboxes.cf:

File: /etc/postfix/dbmail_mailboxes.cf

hosts = 127.0.0.1
dbname = dbmail
user = dbmail
password = password_of_dbmail
query    = SELECT 1 FROM dbmail_aliases WHERE alias='%s' LIMIT 1

Test MySQL queries:

Terminal:

# postmap -q 'test@domain.ltd' mysql:/etc/postfix/dbmail_recipients.cf
test@domain.ltd

# postmap -q 'domain.ltd' mysql:/etc/postfix/dbmail_domains.cf 
1

# postmap -q 'test@domain.ltd' mysql:/etc/postfix/dbmail_mailboxes.cf 
1

It's now OK to send a test email with command mail (provided by package mailx) after restarting Postfix service:

Terminal:

# /etc/init.d/postfix restart
# mail -s "test" test@domain.ltd < /etc/hosts

Log in Postfix log file /var/log/maillog:

Aug 14 06:40:20 c60 postfix/pickup[6017]: B89A141FAD: uid=0 from=<root>

Aug 14 06:40:20 c60 postfix/qmgr[6016]: B89A141FAD: removed

Configure Roundcube to work with DBMail

Just change below setting in /var/www/roundcubemail/config/main.inc.php':

File: /var/www/roundcubemail/config/main.inc.php

$rcmail_config['imap_auth_type'] = "LOGIN";

Restart Apache, you can now view sent email after logging into Roundcube webmail:

Terminal:

# /etc/init.d/httpd restart

Replace Dovecot with Cyrus-SASL as SMTP SASL auth daemon

Postfix uses 'dovecot' as SASL type in iRedMail by default, since Dovecot will be replaced by DBMail, we cannot use Dovecot anymore. So we're going to install Cyrus-SASL libraries, and use daemon 'saslauthd' for SMTP SASL auth.

In this section, we will:

Install Cyrus-SASL libraries.
Configure Cyrus-SASL.
Running and testing Cyrus-SASL auth daemon 'saslauthd' immediately.

Install Cyrus-SASL libraries

Cyrus-SASL libraries are available in default yum repositories.

For RHEL, they're available in yum repository rhn or CD/DVD images.
For CentOS and Scientific Linux, they're available in default yum repositories.

Terminal:

# yum install cyrus-sasl cyrus-sasl-lib cyrus-sasl-sql cyrus-sasl-plain cyrus-sasl-md5

Configure Cyrus-SASL

Configure Cyrus-SASL daemon config file:

On RHEL/CentOS/Scientific Linux 5.x:
- On i386, it's /usr/lib/sasl2/smtpd.conf
- On x86_64, it's /usr/lib64/sasl2/smtpd.conf
On RHEL/CentOS/Scientific Linux 6.x, it's /etc/sasl2/smtpd.conf

File: smtpd.conf

pwcheck_method: saslauthd
mech_list: plain login
auxprop_plugin: sql
sql_engine: mysql
sql_hostnames: 127.0.0.1
sql_user: dbmail
sql_passwd: password_of_dbmail
sql_database: dbmail
sql_verbose: no
sql_select: SELECT passwd FROM dbmail_users WHERE userid = '%u'

Update /etc/sysconfig/saslauthd (Refer to manual page saslauthd(8) for more information):

File: /etc/sysconfig/saslauthd

SOCKETDIR=/var/spool/postfix/var/run/saslauthd
MECH=rimap
FLAGS='-O 127.0.0.1 -r'

Note:

We set SOCKETDIR to /var/spool/postfix/var/run/saslauthd/ so that Postfix works fine under chroot.
Don’t forget ‘-r’ in FLAGS. It will force saslauthd daemon uses full email address ad user name.

Create directory used to store saslauthd daemon socket file:

Terminal:

# mkdir -p /var/spool/postfix/var/run/saslauthd/

Start service saslauthd now, and make it auto start when system boot:

Terminal:

# /etc/init.d/saslauthd restart
# chkconfig --level 345 saslauthd on

Test saslauthd and troubleshooting

Terminal:

# testsaslauthd -f /var/spool/postfix/var/run/saslauthd/mux -u 'test@domain.ltd' -p 'mypass'
0: OK "Success."

Note: If you're running DBMail-3.0.0-rc1, you will always get 0: NO "authentication failed", because DBMail-3.0.0-rc1 has a compatibility issue with Cyrus-SASL.

Enable Cyrus-SASL in Postfix

Terminal:

# postconf -e smtpd_sasl_path='smtpd' smtpd_sasl_type='cyrus'

Restarting Postfix service to make it work:

Terminal:

# /etc/init.d/postfix restart

You can now send email with Roundcube webmail.
