I have installed qmail on linux redhat 9.
I am able to send email using .qmail file.

I created a .qmail file: .qmail-softb having following content:

¦preline /usr/bin/procmail procmail-test ¦¦ exit 111
&bounce@localhost.localdomain

Then I created procmail-test file containg following code:

:0 c
! test@localhost.localdomain

I used the following command in command line:

#mail softb
Subject: test sub
test msg body
Cc:
^D

As a result the mail was send to bounce@localhost.localdomain email as well as forwarded to test@localhost.localdomain.

But when I try to change the content in subject and message body, the content is not changing.

My sample requirement as followiing below:

.qmail file content:
---------------------
&james@xyz.com
¦ preline /usr/bin/procmail /var/qmail/test/procmail-test

[u]Sample mail[/u:
---------------------------------------------
To: james@xyz.com
From: Mosiur
Subject: Hi #firstName#
Body:
