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=-L/usr/local/lib -lsqlite3 -lpthread'

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.
