20<h2>Introduction</h2>
21
22<p> The Postfix sqlite map type allows you to hook up Postfix to a
23SQLite database. This implementation allows for multiple sqlite
24databases: you can use one for a virtual(5) table, one for an
25access(5) table, and one for an aliases(5) table if you want.  </p>
26
27<h2>Building Postfix with SQLite support</h2>
28
29<p> The Postfix SQLite client utilizes the sqlite3 library,
30which can be obtained from: </p>
31
32<blockquote>
33    <p> http://www.sqlite.org/ </p>
34</blockquote>
35
36<p> In order to build Postfix with sqlite map support, you will
37need to add to CCARGS the flags -DHAS_SQLITE and -I with the directory
38containing the sqlite header files, and you will need to add to
39AUXLIBS the directory and name of the sqlite3 library, plus the
40name of the standard POSIX thread library (pthread).  For example:
41</p>
42
43<blockquote>
44<pre>
45make -f Makefile.init makefiles \
46     'CCARGS=-DHAS_SQLITE -I/usr/local/include' \
47     'AUXLIBS=-L/usr/local/lib -lsqlite3 -lpthread'
48</pre>
49</blockquote>
50
51<p> Then, just run 'make'.</p>
52
53<h2>Using SQLite tables</h2>
54
55<p> Once Postfix is built with sqlite support, you can specify a
56map type in main.cf like this: </p>
57
58<blockquote>
59<pre>
60alias_maps = sqlite:/etc/postfix/sqlite-aliases.cf
61</pre>
62</blockquote>
63
64<p> The file /etc/postfix/sqlite-aliases.cf specifies lots of
65information telling Postfix how to reference the sqlite database.
66For a complete description, see the sqlite_table(5) manual page. </p>
67
68<h2>Example: local aliases </h2>
69
70<pre>
71#
72# sqlite config file for local(8) aliases(5) lookups
73#
74
75# Path to database 
76dbpath = /some/path/to/sqlite_database
77
78# See sqlite_table(5) for details.
79query = SELECT forw_addr FROM mxaliases WHERE alias='%s' AND status='paid'
80</pre>
81
82<h2>Additional notes</h2>
83
84<p> The SQLite configuration interface setup allows for multiple
85sqlite databases: you can use one for a virtual table, one for an
86access table, and one for an aliases table if you want. </p>
87
88<h2>Credits</h2>
89
90<p> SQLite support was added with Postfix version 2.8. </p>
