+Quick Amavis setup
+==================
+
+By default, amavis doesn't use a database. To configure this
+behaviour, you first need to create a dedicated database. This step is a
+bit manual since no *ready-to-use* SQL schema is provided by
+amavis. The information is located inside README files, one for `MySQL
+<http://www.amavis.org/README.sql-mysql.txt>`_ and one for `PostgreSQL
+<http://www.amavis.org/README.sql-pg.txt>`_.
+
+Then, you must tell amavis to use this database for lookups and
+quarantined messages storing. Here is a working configuration sample::
+
+  @lookup_sql_dsn =
+    (['DBI:<driver>:database=<database>;host=<dbhost>;port=<dbport>', '<dbuser>', '<password>]']);
+
+  @storage_sql_dsn =
+    (['DBI:<driver>:database=<database>;host=<dbhost>;port=<dbport>', '<dbuser>', '<password>]']);
+
+  $virus_quarantine_method = 'sql:';
+  $spam_quarantine_method = 'sql:';
+  $banned_files_quarantine_method = 'sql:';
+  $bad_header_quarantine_method = 'sql:';
+
+  $virus_quarantine_to = 'virus-quarantine';
+  $banned_quarantine_to = 'banned-quarantine';
+  $bad_header_quarantine_to = 'bad-header-quarantine';
+  $spam_quarantine_to = 'spam-quarantine';

+amavis to allow quarantined messages release, read this :ref:`section

+
+   Amavis configuration allows for separate lookup and storage
+   databases but Modoboa doesn't support it yet.
