Corrected opening/closing quotation marks («word» -> »word«). * VirtualMailManager/VirtualMailManager.py: Renamed VirtualMailManager.__chkEmailadress to VirtualMailManager.__chkEmailAddress. * ChangeLog: Added to repository.

Installation Prerequisites
You should already have installed and configured Postfix, Dovecot and
PostgreSQL.
You have to install Python and pyPgSQL to use the Virtual Mail Manager.


Configuring PostgreSQL

* /etc/postgresql/8.2/main/pg_hba.conf
    # IPv4 local connections:
    host    mailsys     +mailsys    127.0.0.1/32          md5

    # reload configuration
    /etc/init.d/postgresql-8.2 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 Postfix and Dovecot
    connecting to PostgreSQL:
    psql template1
    
    # create database
    CREATE DATABASE mailsys ENCODING 'UTF8';
    # connect to the new database
    \c mailsys
    # import db structure
    \i /path/to/create_tables.pgsql

    # create users and group
    CREATE USER postfix ENCRYPTED password 'DB PASSWORD for Postfix';
    CREATE USER dovecot ENCRYPTED password 'DB PASSWORD for Dovecot';
    CREATE ROLE mailsys WITH USER postfix, dovecot;

    # set permissions
    GRANT SELECT ON dovecot_password, dovecot_user TO dovecot;
    GRANT SELECT ON postfix_alias, postfix_maildir, postfix_relocated,
    postfix_uid, postfix_gid, postfix_transport 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
  chmod 771 /srv/mail
  chgrp -R mail /srv/mail
  chmod 751 /srv/mail/*

Configuring Dovecot

* /etc/dovecot/dovecot.conf
    # all your other settings
    mail_location = maildir:~/Maildir
    mail_extra_groups = mail
    first_valid_uid = 70000
    first_valid_gid = 70000
    protocol lda {
      postmaster_address = postmaster@domain.tld
    }
    auth default {
      mechanisms = cram-md5
      passdb sql {
        args = /etc/dovecot/dovecot-sql.conf
      }
      userdb sql {
        args = /etc/dovecot/dovecot-sql.conf
      }
      user = nobody
      socket listen {
        master {
          path = /var/run/dovecot/auth-master
          mode = 0600
        }
        client {
          path = /var/spool/postfix/private/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 = HMAC-MD5
    password_query = SELECT "user", password FROM dovecot_password WHERE "user"= '%u'
    user_query = SELECT home, uid, gid FROM dovecot_user WHERE userid = '%u'

Provide a root SETUID copy of Dovecot's deliver agent for Postfix

    mkdir -p /usr/local/lib/dovecot
    chmod 700 /usr/local/lib/dovecot
    chown nobody /usr/local/lib/dovecot
    cp /usr/lib/dovecot/deliver /usr/local/lib/dovecot/
    chmod u+s /usr/local/lib/dovecot/deliver


Start or restart Dovecot


Configuring Postfix's master.cf

    # Add Dovecot's deliver agent
    dovecot   unix  -       n       n       -       -       pipe
      flags=DRhu user=nobody:mail argv=/usr/local/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} -n -m ${extension}



Configuring Postfix's main.cf

    # virtual domains
    virtual_mailbox_domains = pgsql:/etc/postfix/pgsql-transport.cf
    virtual_alias_maps = pgsql:/etc/postfix/pgsql-virtual_alias_maps.cf
    transport_maps = pgsql:/etc/postfix/pgsql-transport.cf
    virtual_minimum_uid = 70000

    virtual_gid_maps = pgsql:/etc/postfix/pgsql-virtual_gid_maps.cf
    virtual_mailbox_base = /
    virtual_mailbox_maps = pgsql:/etc/postfix/pgsql-virtual_mailbox_maps.cf

    # dovecot LDA
    dovecot_destination_recipient_limit = 1
    virtual_transport = dovecot:

    # dovecot SASL
    smtpd_sasl_type = dovecot
    smtpd_sasl_path = private/auth
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_local_domain = $myhostname
    smtpd_sasl_security_options = noplaintext, noanonymous



Installing the Virtual Mail Manager and configure the rest

    Installing from SVN
    after checking out type
        ./install
    edit all the pgsql-*.cf files in /etc/postfix

    reload postfix

    # configure the Virtual Mail Manager
    vmm configure

    # for help type
    vmm help
