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.

  ‣ each domain may have one or more alias domain names
  ‣ activate or deactivate services (SMTP, POP, 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

  ‣ unique user identifier (UID) per user

• Alias features

  ‣ supports multiple destinations per e-mail alias
  ‣ destinations can be deleted separately

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``.
