Eh. No. I think you have it confised with fetchmail;-). Procmail is
used to "process" mail in a variety of ways... Read the procmailex
manpage to see some nice examples.

You can use procmail to do the local mailbox delivery by way of the
mailbox_command. This is good, since you'll have procmail run for each
delivered mail without having to fiddle with any (fake) .forward file,
as you would if you only wanted procmail for _some_ users...
This is snipped from a main.cf.dist on one of my Mandriva systems...
Explains it better than I do:-):
----
# The mailbox_command parameter specifies the optional external
# command to use instead of mailbox delivery. The command is run as
# the recipient with proper HOME, SHELL and LOGNAME environment settings.
# Exception:  delivery for root is done as $default_user.
#
# Other environment variables of interest: USER (recipient username),
# EXTENSION (address extension), DOMAIN (domain part of address),
# and LOCAL (the address localpart).
#
# Unlike other Postfix configuration parameters, the mailbox_command
# parameter is not subjected to $parameter substitutions. This is to
# make it easier to specify shell syntax (see example below).
#
# Avoid shell meta characters because they will force Postfix to run
# an expensive shell process. Procmail alone is expensive enough.
#
# IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
# ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.
#
#mailbox_command = /some/where/procmail
#mailbox_command = /some/where/procmail -a "$EXTENSION"
