I have only one mail program.
Anyway - I try this:

#!/bin/sh

PERCENT=$1

echo "From: \"Quota Subsystem\" <postmaster at domain.off>
To: $USER
Subject: E-Mail Quota Warning
Mime-Version: 1.0
Content-Type: text/plain; charset=koi8-r
Content-Transfer-Encoding: 8bit

Your mailbox is $PERCENT% full. If it overfill - you will can not get 
new email.
Please clean up your mailbox.

And all ok. But I have this headers:
Return-path: <dmail at mx.domain.off>
Envelope-to: proskurin-kv at domain.off
Delivery-date: Tue, 21 Oct 2008 13:56:03 +0400
Received: from dmail by mx.domain.off with local (Exim 4.69 (FreeBSD))
	(envelope-from <dmail at mx.domain.off>)
	id 1KsDy7-000L9d-0H
	for proskurin-kv at domain.off; Tue, 21 Oct 2008 13:56:03 +0400
From: "Quota Subsystem" <postmaster at domain.off>
TO: proskurin-kv at domain.off
Subject: E-Mail Quota Warning
Sender: Dovecot Mail <dmail at mx.domain.off>

As you see - it have sender header and dont looks good im clients MUA. 
But it is a "problem" of my MTA and not for this list.


P.S. Oh. All I ask it is to explain HOW launch of quota-warning.sh work 
to make me free to write my own script.

Anyway - thank you for you answers.
