No, the mistake is that Plusnet are comparing it against 0.15. I've attached the results from the header analyser - for this message they should have compared against 0.075

Oh yes! Thank you! "Category filter value" (presumably the GT3) halves the effective spam setting.... I think I'm going to join you on the Quarantine option

What I don't understand is this part of the header of my second example:
X-Ec-Messenger-Email: zopa@xxxxxx.plus.com
X-Pstn-Levels: (S: 0.00000/96.96317 CV:99.9000 )
X-Pstn-Settings: 1 (0.1500:0.1500) cv gt3 gt2 gt1
X-Pstn-Addresses: from <zopalenderemail@messages.zopa.com> [380/17]
X-Pn-Pstn: Spam 1
X-Pn-Virus-Filtered: by PlusNet MXCore (v4.00)
X-Pn-Spam-Filtered: by PlusNet MXCore (v4.00)
Postini scores it as ZERO, but Plusnet says it's spam. Huh?

Zero is less than 0.15 so it is considered spam by Postini - the scale works the other way round to what you'd expect - zero is definitely spam, 99 is absolutely certain it's not spam.
Try pasting the headers in to http://www.postini.com/support/header_analyzer.php

Jim,
I'm not sure about that message. Can you paste the full headers in to the header analyser and see what it says.

Just received a perfectly genuine email and the only possible reason for it falling foul of the spam filter is that it included a link to a web page http://www.dorset-ramblers.co.uk/EastDorset/index.html
