I'm not an Orcon customer but a friend is. I've just found a bunch of perfectly fine emails from him in my spam folder because I use dspam and filter on the X-DSPAM-Result header. It looks like Orcon is also using dspam, but they're passing their customers outgoing messages through it and incorrectly marking them as spam. What's up with that?

Here's a snippet of the headers from Orcon on a recent message:

X-DSPAM-Check: by mx4.orcon.net.nz on Mon, 15 Nov 2010 19:50:25 +1300
X-DSPAM-Result: Spam
X-DSPAM-Processed: Mon Nov 15 19:50:25 2010
X-DSPAM-Confidence: 0.4568
X-DSPAM-Probability: 0.9474


I'm not sure what good it does anybody to wrongly mark customer messages as spam and then launch them into the world. In addition to that, dspam is a learning system and needs training. There's no feedback path here; I can't exactly tag the message as good and send it back round to Orcon for retraining, so it's probably way off the mark in it's judgement.

Is there a way to contact someone at Orcon and get this reviewed or disabled?
