"Interested Third Party" question

Recommended Posts

I use a mailbox-forwarding service at acm.org for my primary email. They used to filter spam with Postini, but switched to Mailroute about a year ago. Mailroute spam filtering is a great improvement over Postini, catching over 95% of spam with very few false positives.

When the occasional spam makes it through I submit it to SpamCop. Starting immediately after the switch to Mailroute I noticed my SpamCop reports included an "Interested third party" recipient, which I assumed was someone at Mailroute.

Recently (about a month ago), this "interested third party" email disappeared from my reports, and since then Mailroute's spam filtering has gotten less effective, letting through really obvious spam.

Some questions:

  1. Does SpamCop have (or did they have) a direct line to Mailroute to submit spam for analysis and tracking?
  2. Was the "Interested third party" (tj at terramar.net) a Mailroute spam tracking address?
  3. What changed at SpamCop such that this third party is no longer receiving spam reports?

Thanks.

Hi, jhg,

2. Was the "Interested third party" (tj at terramar.net) a Mailroute spam tracking address?

3. What changed at SpamCop such that this third party is no longer receiving spam reports?

2. It does seem that there's a relationship between Mailroute and terramar: see Robtex entry for Mailroute.net.

3. Please explain why you believe there to have been a change in SpamCop. I would suspect that the change was on the Mailroute end rather than on the SC end.

I don't know if it was SC or mailroute that changed.

I guess the real question is why that address was an "interested third party" to begin with. How did terramar get "interested third party" status for spam arriving via mailroute?

If a email administrator wants reports on their IP's (even if not injection point (source) they can get one
