 Installation Prerequisites
-You should already have installed and configured Postfix, Dovecot and
-PostgreSQL.
+You should already have installed and configured Postfix, Dovecot ≥ 1.2.0
+and PostgreSQL.
 
 The Virtual Mail Manager depends on:
-    - Python (>= 2.4.0)
-    - Psycopg 2¹ or pyPgSQL²
+    - Python (≥ 3.2)
+    - Psycopg¹ (≥ 2.0)
 
-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 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
