+define(`TITLE', `Children Protection for Postfix-based EMail-Server')
+define(`CONTENT', `
+This small tool implements a whitelist on a Postfix mail-server. It prevents certain recipient addresses (your kids ones) from receiving mail from any not whitelisted address. Any mail from not whitelisted senders is redirected to a delegate (a parent).
+
+Code is here <a href="http://files.a385e-5.de/files/ChildProt-0.9.tar.gz">http://files.a385e-5.de/files/ChildProt-0.9.tar.gz</a>
+
+Configure it by adding this line into the <em>master.cf</em> of the Postfix installation:
+<pre>childprot unix  -       n       n       -       25      spawn user=mail argv=/opt/sbin/ChildProt</pre>
+and this to the <em>main.cf</em>:
+<pre class="brush: text; gutter: false">smtpd_recipient_restrictions =
+  [...]
+  check_policy_service unix:private/childprot
+  [...]</pre>
+The restricted recipients and the whitelists are stored in an SQLite3 database:
+<pre class="brush: sql; gutter: false">CREATE TABLE child_address_t (
+  child INTEGER REFERENCES child_t(id),
+  address TEXT
+);
+
+CREATE TABLE child_t (
+  id INTEGER PRIMARY KEY,
+  name TEXT,
+  delegate TEXT
+);
+
+CREATE TABLE whitelist_t (
+  child INTEGER REFERENCES child_t(id),
+  address TEXT
+);
+
+CREATE VIEW child_v AS
+  SELECT c.id as id,
+         c.delegate as delegate,
+         ca.address as address
+  FROM child_t c,
+       child_address_t ca
+  WHERE c.id = ca.child;</pre>
+Restricted persons together with their delegates are added to the table <em>child_t</em>, multiple addresses can be assigned to those persons in <em>child_address_t</em>. Whitelists per person are maintained in <em>whitelist_t</em>.
+
+The tool is querying the view <em>child_v</em>.
