[clug-talk] Anyone else getting a lot of supposed bounced mail?

I seem to be getting a lot of mail coming through my server, reporting
"Mail Delivery Status (Undeliverable)", (or others with similar subjects).
When I check the headers, these all appear to originate outside my network,
and the embedded message itself is clearly spam. However, I'm a little
worried I'm inadvertently relaying mail. Can I get a second opinion? Here's

Subject: Message status - undeliverable
Obviously, the open2space.com domain is mine. Some of the header is legit -
the first 7 or so lines (up to the X-Spam-Status) are typical for my mail,
and the 192.168.0.5 address is correct for my mail server (internal address).
But this looks to originate from fibretek.com. My network does not have a
jeffreycaselk account, nor do I use Groupwise (or Eudora, or Exchange as
reported by some of the other messages) Is this a bad relay attempt? Should
I be locking down my network even more? (My mail server has never been
configured as a mail relay, but I did have some issues in the not too distant
past that required some tweaking, maybe I inadvertently opened something? Or
can I safely ignore this and wait until spamassassin decides this is spam?
Regardless I'll be looking into my server settings, but I am curious if anyone
else is seeing these messages.
