Regarding this report:

http://www.spamcop.net/sc?id=z924259737z3b...db10c6e7c3d0caz

Repeating the relevant section

This was mail I had forwarded from comcast.net to spamcop.net. Would it be correct to interpret this as a misconfigured comcast server? (I didn't think that 192.168 was routable, but it has been a while since I've worked in this area).

If so, who would I contact at comcast to point this out?

Edit: by the way...

goodeatingg.com is reachable (some sort of diet spam). It resolves to 217.170.20.22

Somehow the automated link testing didn't catch this.

I'd say you need to step back, take a deep breath, and head off to do some research on how to read headers .... links provided in the SpamCop FAQ here, links at the top of the page.

Verizon Internet Services Inc. VZGNI-PUB-1 (NET-138-88-0-0-1)

138.88.0.0 - 138.88.255.255

AT&T WorldNet Services ATTPLS (NET-204-127-0-0-1)

204.127.0.0 - 204.127.255.255

(and in this case, AT&T = ComCast)

mx53.cesmail.net is one of JT's servers, which then passed it on bis an internal network to blade5.cesmail.net, another of JT's servers.

I don't see any ComCast mis-configured server evidence in your sample.

goodeatingg.com is reachable (some sort of diet spam).  It resolves to 217.170.20.22

Tons of existing Topics/Discussion in the Reporting Help Forum, some in this Forum, FAQ entries exist .... let's wait until you do some of that initial research before starting yet another one on this specific iem right now.
