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> 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>Additional notes</h2> + +<p> The SQLite configuration interface setup allows for multiple +sqlite databases: you can use one for a virtual table, one for an +access table, and one for an aliases table if you want. </p> + +<h2>Credits</h2> + +<p> SQLite support was added with Postfix version 2.8. </p> + +<ul> + +<li>Implementation by Axel Steiner</li> +<li>Documentation by Jesus Garcia Crespo</li> + +</ul> + +</body> + +</html> |
