Maybe if you do, you can send them a friendly nod..
Seems someone has decided to use their backscatter for sending spam
messages..
From: Mail Delivery System <mailer-dae...@pmgd06.wadax.ne.jp>
Subject: Undelivered Mail Returned to Sender
<quote>
This is the mail system at host pmgd06.wadax.ne.jp.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.

Typical, the server allows forged MAIL FROM and From, gets blocked by
the receiving system, and then attempts to notify the sender, forged in
this case, and issue an NDR, and of course the NDR contains the original
spam message, but the NDR's can get past the forgery restrictions, as it
is from Mailer-Daemon.
They need to prevent forged 'MAIL FROM' and need to prevent backscatter.
Their 'postmaster' address in the 'cc' to this post.
Everyone should remember, they should have checks that the MAIL FROM can
only originate from an address that resides on their system.
Have a happy friday everyone..
