How does the headers of a real massage (from your server) looks like? It’s strange that the bounced messages in Pastebin only have one “Received” header, without IP information.
I just looked at the last message I got and it has 10 headers with Received, X-Received or Received-SPF, with a lot of IP information.
If they are spoofing the email, then “DomainKeys Identified Mail (DKIM)” may help http://www.dkim.org/ . I never deployed it to a server, so you must seek advice from someone with real word experience.
