Problem accesing arguments

Hi,

I write the following simple RCFILE:

ARG1=$1
ARG2=$2
ARG3=$3

:0
*
| ( echo ARG1=$ARG1 ;\
    echo ARG2=$ARG2 ;\
    echo ARG3=$ARG3 ;\
    echo UID=$UID; \
    echo DEFAULT=$DEFAULT \
  ) >/dev/console



I put it as /etc/procmailrcs/test
I chown it to user test, group users and permisions -rw-------
Directory /etc/procmailrcs belongs to root.root with permisions drwx------

Then, running as root, if I execute:

cd /etc/procmailrcs
echo "" | procmail -m test one two three

it writes to the console:

ARG1=one
ARG2=two
ARG3=three
UID=0
DEFAULT=/var/spool/mail/root

This is correct, as described by the manual.

But executing:

echo "" | procmail -m /etc/procmailrcs/test one two three

writes to the console:

ARG1=
ARG2=
ARG3=
UID=521
DEFAULT=/var/spool/mail/test

The DEFAULT and UID are the expected, but the arguments are lost.

Can anyone explain me whay?
