Spammers using my SMTP...

I have noticed lately that my Queue list has been huge... When I view the QMail Queue list with qmHandle I see lots of this:

1406393 (9, R)
Return-path:
From: MAILER-DAEMON@MYDOMAIN.COM
To: info@mymobilephone.com
Subject: failure notice
Date: 1 Sep 2004 19:34:14 -0000
Size: 35897 bytes

By the end of the day I will hundreds of these failure messages. Currently I am just running: './qmHandle -Sfailure' every 5 hours to clear it all out.

I know it's spammers, I viewed a few of the messages...

I also did: telnet relay-test.mail-abuse.org
It said only one got through.... the 'whatever%domain.com'

Basically, I just want some advice on how to stop these people from connecting to my clients mail servers and spamming.

The last thing I want is to get black listed on spam databases.

I am running PLESK7
