To prevent spoofing, you can enable SPF for your domain (SuSE should do so

Please folks, this is exactly the reason why you should NOT send bounces in
reply to virusses. I'm very disappointed that SuSE is still not aware of the
implications of this annoying behaviour. To summarize, only send warnings to
authenticated senders otherwise you might be sending it to a spoofed sender
Basically, SPF means that you insert a TXT record into your DNS zone that
specifies which IP-addresses and MX servers are allowed to send mail with
a FROM that contains your domain name.
Check the headers for your unsubscription address
