Compile And Install Postfix

$ make
$ make install

Installing Hiredis Client Library

You can clone the code at https://github.com/antirez/hiredis/

$ make
$ make install

Optionally you can also add the folder(/usr/local/lib - default hiredis install folder) to ld.so.conf if required, so that libhiredis.so is resolvable.

Testing Lookup

To test the lookup table you can postmap the string as follows

$ postmap -q "string" redis:/etc/postfix/lookup.cf

Contents of lookup.cfg:
host = localhost
port = 6379

Configuration

The configuration file support two attributes, host and port. The default host is 127.0.0.1 and port is 6379.

Example:
host = redisdb.example.com
port = 6379
