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``.
