VMM/common: Added function human_size().
Installation Prerequisites
You should already have installed and configured Postfix, Dovecot and
PostgreSQL.
The Virtual Mail Manager depends on:
- Python (>= 2.4.0)
- Psycopg 2¹ or pyPgSQL²
If you are using Python <= 2.5.0:
- if you want to store your users' passwords as PLAIN-MD4 digest in
the database, vmm will try to use Crypto.Hash.MD4 from PyCrypto³.
- if you are using Dovecot >= v1.1.0 and you want to store your users'
passwords as SHA256 or SSHA256 hashes, vmm will try to use
Crypto.Hash.SHA256 from PyCrypto². For SHA256/SSHA256 you should have
at least use PyCrypto in version 2.1.0alpha1.
When the Crypto.Hash module couldn't be imported, vmm will use
dovecotpw/doveadm, if the misc.password_scheme setting in the vmm.cfg
is set to PLAIN-MD4, SHA256 or SSHA256
[1] Psycopg: <http://initd.org/psycopg/> (Debian: python-psycopg2)
[2] pyPgSQL: <http://pypgsql.sourceforge.net/> (Debian: python-pgsql)
[3] PyCrypto: <http://www.pycrypto.org/> (Debian: python-crypto)
Configuring PostgreSQL
(for more details see: http://vmm.localdomain.org/PreparingPostgreSQL)
* /etc/postgresql/8.4/main/pg_hba.conf
[ if you prefer to connect via TCP/IP ]
# IPv4 local connections:
host mailsys +mailsys 127.0.0.1/32 md5
[ if you want to connect through a local Unix-domain socket ]
# "local" is for Unix domain socket connections only
local mailsys +mailsys md5
# reload configuration
/etc/init.d/postgresql-8.4 force-reload
* Create a DB user if necessary:
DB Superuser:
createuser -s -d -r -E -e -P $USERNAME
DB User:
createuser -d -E -e -P $USERNAME
* Create Database and db users for vmm, Postfix and Dovecot
connecting to PostgreSQL:
psql template1
# create users, group and the database
CREATE USER vmm ENCRYPTED PASSWORD 'DB PASSWORD for vmm';
CREATE USER dovecot ENCRYPTED password 'DB PASSWORD for Dovecot';
CREATE USER postfix ENCRYPTED password 'DB PASSWORD for Postfix';
CREATE ROLE mailsys WITH USER postfix, dovecot, vmm;
CREATE DATABASE mailsys WITH OWNER vmm ENCODING 'UTF8';
\q
# connect to the new database
psql mailsys vmm -W -h 127.0.0.1
# either import the database structure for Dovecot v1.0.x/v1.1.x
\i /path/to/create_tables.pgsql
# or import the database structure for Dovecot v1.2.x
\i /path/to/create_tables-dovecot-1.2.x.pgsql
# set permissions
GRANT SELECT ON dovecot_password, dovecot_user TO dovecot;
GRANT SELECT ON postfix_alias, postfix_gid, postfix_maildir,
postfix_relocated, postfix_transport, postfix_uid TO postfix;
# leave psql
\q
Create directory for your mails
mkdir /srv/mail
cd /srv/mail/
mkdir 0 1 2 3 4 5 6 7 8 9 a b c d e f g h i j k l m n o p q r s t u v w x y z

after cloning from the hg repo or extracting the archive change into the
new directory and type:
./install.sh
edit all the pgsql-*.cf files in /etc/postfix
reload postfix
