+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.
+

+
+The Postfix SQLite client utilizes the sqlite3 library, which can be obtained
+from:
+
+    http://www.sqlite.org/
+
+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:
+
+    make -f Makefile.init makefiles \
+         'CCARGS=-DHAS_SQLITE -I/usr/local/include' \
+         'AUXLIBS_SQLITE=-L/usr/local/lib -lsqlite3 -lpthread'
+
+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.
+
+    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.
+
+Then, just run 'make'.

+
+Once Postfix is built with sqlite support, you can specify a map type in
+main.cf like this:
+
+    alias_maps = sqlite:/etc/postfix/sqlite-aliases.cf
+
+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.

+
+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.

+SQLite support was added with Postfix version 2.8.
