Postfix and Procmail setup

[Lorenzo Rossi <condor_rl@libero.it>]

Hi,

I would like to change my "way" to read e-mails.

Now I read e-mail using:

FETCHMAIL to get e-mail from my ISP, it pass them to POSTFIX, and I read
them using EVOLUTION.

I would like to use PROCMAIL to store e-mail in different boxs, and then
read e-mails with pine.

The problem is: I do not know if I need to change postfix configuration
to use procmail, and I do not know how to configure procmail..:(

In my "main.cf" Postfix configuration file, is present the line below:

mailbox_command = procmail -a "$EXTENSION"


I do not know how to procede..
Can you help me?

Thanks in advance
Lorenzo
