.procmailrc storage of sent emails

[ogl...@yahoo.com]

Hello

I would like to storage the emails that I have sent.

Example:

So, I am sending the message from my account, and would like to send
the copy of that email (with the changed subject) to, example, gmail,
ie to storage it:

From: me@server1
To: somebody@server2
Subject: "Subject"

What should be written in .procmailrc file to do the additional
forwarding (copying) of that sent email, to my account me@gmail, with
the subject: "Sent - Subject";

(This changed subject is because of filtering at gmail)

Thanks.
