+
+<hr>
+
+<h2>Introduction</h2>
+
+<p> The Postfix sqlite map type allows you to hook up Postfix to a
+SQLite database. This implementation allows for multiple sqlite
+databases: you can use one for a virtual(5) table, one for an
+access(5) table, and one for an aliases(5) table if you want.  </p>
+
+<h2>Building Postfix with SQLite support</h2>
+
+<p> The Postfix SQLite client utilizes the sqlite3 library,
+which can be obtained from: </p>
+
+<blockquote>
+    <p> http://www.sqlite.org/ </p>
+</blockquote>
+
+<p> In order to build Postfix with sqlite map support, you will
+need to add to CCARGS the flags -DHAS_SQLITE and -I with the directory
+containing the sqlite header files, and you will need to add to
+AUXLIBS the directory and name of the sqlite3 library, plus the
+name of the standard POSIX thread library (pthread).  For example:
+</p>
+
+<blockquote>
+<pre>
+make -f Makefile.init makefiles \
+     'CCARGS=-DHAS_SQLITE -I/usr/local/include' \
+     'AUXLIBS_SQLITE=-L/usr/local/lib -lsqlite3 -lpthread'
+</pre>
+</blockquote>
+
+<p> If your SQLite shared library is in a directory that the RUN-TIME
+linker does not know about, add a "-Wl,-R,/path/to/directory" option after
+"-lsqlite3". </p>
+
+<p> Postfix versions before 3.0 use AUXLIBS instead of AUXLIBS_SQLITE.
+With Postfix 3.0 and later, the old AUXLIBS variable still supports
+building a statically-loaded SQLite database client, but only the new
+AUXLIBS_SQLITE variable supports building a dynamically-loaded or 
+statically-loaded SQLite database client.  </p>
+
+<blockquote>
+ 
+<p> Failure to use the AUXLIBS_SQLITE variable will defeat the purpose
+of dynamic database client loading. Every Postfix executable file
+will have SQLITE database library dependencies. And that was exactly
+what dynamic database client loading was meant to avoid. </p>
+ 
+</blockquote>
+
+<p> Then, just run 'make'.</p>
+
+<h2>Using SQLite tables</h2>
+
+<p> Once Postfix is built with sqlite support, you can specify a
+map type in main.cf like this: </p>
+
+<blockquote>
+<pre>
+alias_maps = sqlite:/etc/postfix/sqlite-aliases.cf
+</pre>
+</blockquote>
+
+<p> The file /etc/postfix/sqlite-aliases.cf specifies lots of
+information telling Postfix how to reference the sqlite database.
+For a complete description, see the sqlite_table(5) manual page. </p>
+
+<h2>Example: local aliases </h2>
+
+<pre>
+#
+# sqlite config file for local(8) aliases(5) lookups
+#
+
+# Path to database 
+dbpath = /some/path/to/sqlite_database
+
+# See sqlite_table(5) for details.
+query = SELECT forw_addr FROM mxaliases WHERE alias='%s' AND status='paid'
+</pre>
+
+<h2>Credits</h2>
+
+<p> SQLite support was added with Postfix version 2.8. </p>
