This is not so. The read_hash() routine reads the file into a memory-based
associative array (hash), and does it at the time when it is called,
which is at the time amavisd.conf is being processes, which happens
only at the initial startup.

To make amavisd consult external database for every mail being processed,
thus allowing for dynamically updated lookup tables, one has to use
a SQL or LDAP lookup table, or do a perl 'tie' of a hash variable
to a database (e.g. cdb or bdb).

For smaller sites that still like to avoid the need for restarts
at lookup table changes, but don't need a full blown SQL server,
I suggest a SQLite -based SQL database, which is contained on a
single file on the same host (no client/server model).
A dataset name entry could look like:

@lookup_sql_dsn =
(["DBI:SQLite:dbname=$MYHOME/sql/mail_prefs.sqlite",'','']);
