If you are the mail admin, then it is likely you are getting an NDR for a mail sent from a spammed address on your domain. ie.
Someone used your companies domain name as a valid mail address to send spam. It was rejected and an NDR was sent to what is most likely postmaster@yourdomain.com.
That NDR message looks like it could be an anispam filter...
I could be wrong though...

Also check out Sobig. As far as Im aware, Sobig Spoofs mail address in your addresss book and then sends itself FROM that adress. So, if I had your address is my adress book and contracted Sobig, My machine would send out a mail from YOUR mail address. If the recipient rejected the mail (cause it is a virus) the NDR would be sent to the from adress, namely YOU... So you get the NDR without ever sending the mail...
