Installation PrerequisitesYou should already have installed and configured Postfix, Dovecot andPostgreSQL.The Virtual Mail Manager depends on:- Python (>= 2.4.0)- Psycopg 2¹ or pyPgSQL²If 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)Create additionally a user and groups for improved security We will create the system user `doveauth'. This user is used in the authentication process. On a Debian GNU/Linux System use this command: adduser --system --home /nonexistent --no-create-home --group \ --disabled-login --gecos "Dovecot IMAP/POP3 authentication user" \ doveauth This will create the doveauth user and group. For Dovecot >= 2.0 we create also the group `dovemail'. Dovecot will assign this group to all Dovecot processes. On a Debian GNU/Linux bases system run: addgroup --system dovemailConfiguring PostgreSQL(for more details see: http://vmm.localdomain.org/installation/postgresql_configuration.html)* /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 database superuser if necessary: # as root run: su - postgres # if you have sudo privileges run: sudo su - postgres # create your superuser, which will be able to create users and databases createuser -s -d -r -E -e -P $USERNAME* As superuser create the database and db users for vmm, Postfix and Dovecot connecting to PostgreSQL: psql template1 # create users, group and the database CREATE ROLE vmm LOGIN ENCRYPTED PASSWORD 'DB PASSWORD for vmm'; CREATE ROLE dovecot LOGIN ENCRYPTED password 'DB PASSWORD for Dovecot'; CREATE ROLE postfix LOGIN ENCRYPTED password 'DB PASSWORD for Postfix'; CREATE ROLE mailsys WITH USER postfix, dovecot, vmm; CREATE DATABASE mailsys WITH OWNER vmm ENCODING 'UTF8'; \q # connect to the new database psql mailsys vmm -W -h 127.0.0.1 # either import the database structure for Dovecot v1.0.x/v1.1.x \i vmm-y.x.z/pgsql/create_tables.pgsql # or import the database structure for Dovecot v1.2.x/v2.x \i vmm-x.y.z/pgsql/create_tables-dovecot-1.2.x.pgsql # leave psql \q # set permissions for your Dovecot and Postfix users # see python set-permissions.py -h for details python vmm-x.y.z/pgsql/set-permissions.py -a -H 127.0.0.1 -U vmmCreate directory for your mails mkdir /srv/mail cd /srv/mail/ mkdir 0 1 2 3 4 5 6 7 8 9 a b c d e f g h i j k l m n o p q r s t u v w x y z chmod 771 /srv/mail chmod 751 /srv/mail/*For Dovecot >= 2.0 read the file Configure.Dovecot_2Configuring Dovecot v1.x* /etc/dovecot/dovecot.conf # all your other settings #disable_plaintext_auth = no mail_location = maildir:~/Maildir first_valid_uid = 70000 first_valid_gid = 70000 protocol lda { postmaster_address = postmaster@YOUR-DOMAIN.TLD } auth default { mechanisms = cram-md5 login plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb sql { args = /etc/dovecot/dovecot-sql.conf } user = doveauth socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 } client { path = /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } } }* /etc/dovecot/dovecot-sql.conf driver = pgsql connect = host=localhost dbname=mailsys user=dovecot password=$Dovecot_PASS default_pass_scheme = CRAM-MD5 password_query = SELECT userid AS "user", password FROM dovecotpassword('%Ln', '%Ld') WHERE %Ls user_query = SELECT home, uid, gid, mail FROM dovecotuser('%Ln', '%Ld')Provide a root SETUID copy of Dovecot's deliver agent for Postfix/!\ Only required with Dovecot v.1.x.
