vmm - a virtual mail manager

============================

Welcome to vmm!

**vmm** is the easy to use and configurable command line tool for

administrators and postmasters, to manage domains, alias-domains, accounts and

relocated mail users. It allows the fast and easy management of mail servers.

vmm is written in Python_. It's designed for installations using Dovecot_ and

Postfix_ with a PostgreSQL_ backend.

Features

========

• General features

  ‣ Unicode/UTF-8 capable (input/storage/output)

  ‣ supports IDN_ (also ccTLDs/ccIDNs and 'new' gTLDs)

  ‣ supports the mailbox format Maildir_ and Dovecot's own high-performance

    mailbox formats single- and multi-\ dbox_

  ‣ configurable basic mailbox structure, including sub-mailboxes

  ‣ multilingual — currently:

     * Dutch

     * English

     * Finnish

     * French

     * German

     * Vietnamese

• Domain features

  ‣ configurable transport_ setting per domain

  ‣ unique group identifier (GID) per domain

  ‣ each domain may have one or more alias domain names

  ‣ activate or deactivate services (SMTP, POP3, IMAP and ManageSieve) for new

    or all accounts of a domain

  ‣ configurable quota limits (size and/or number of messages) for the

    domain's accounts

  ‣ supports relocated_ users

  ‣ the postmaster account can be created automatically when a new domain is

    created

  ‣ supports per-domain catch-all aliases

• Alias domain features

  ‣ alias domain names can be switched between domains

• Account features

  ‣ configurable transport per account

  ‣ activate or deactivate one/more/all services (SMTP, POP3, IMAP and

    ManageSieve) per account

  ‣ configurable quota limit (size and/or number of messages) per user

  ‣ per-account configuration overrides defaults defined by the domain,

    otherwise the setting is inherited

  ‣ unique user identifier (UID) per user

• Alias features

  ‣ supports multiple destinations per e-mail alias

  ‣ destinations can be deleted separately

  ‣ destinations can be interpolated using the original address' local-part

    and domain, allowing aliases to have different meaning in alias domains,

    e.g. with the following defined in example.org::

      postmaster@example.org  →  postmaster+%d@admin.example.org

    If example.com is an alias domain of example.org, the alias will become::

      postmaster@example.org  →  postmaster+example.org@admin.example.org

      postmaster@example.com  →  postmaster+example.com@admin.example.org

Installation Prerequisites

==========================

You already should have installed and configured Postfix and Dovecot with

PostgreSQL support. You also need access to a local or remote PostgreSQL

server.

To verify that your Dovecot and Postfix installation has support for

PostgreSQL use the ``postconf`` and ``dovecot`` commands as shown below::

        hostname ~ # postconf -m | grep pgsql

        pgsql

        hostname ~ # postconf -a | grep dovecot

        dovecot

        hostname ~ # dovecot --build-options | grep postgresql

        SQL drivers: mysql postgresql sqlite

vmm depends on Python (≥ 2.4.0) and Psycopg_ (≥ 2.0) or pyPgSQL_ (≥ 2.5.1).

Psycopg and pyPgSQL are depending on parts of the *eGenix.com mx Base

Distribution* (mxDateTime_ and mxTools_).

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 PyCrypto_

  • 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 PyCrypto. For ``SHA256``/``SSHA256`` you

    should have installed PyCrypto, at least 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 your *vmm.cfg*

  is set to ``PLAIN-MD4``, ``SHA256`` or ``SSHA256``.
