We have it configured to blackhole obvious spam-the problem is that it's not too bright at figuring out what's obvious spam.
But cranking up the sensitivity may help.

And, frankly, we trusted the Google name. The archiving feature works great, and the service has never had a hiccup (in terms of mail flow) since we started using it. No complaints there. Just too much mail going into quarantine that should be blocked outright. I've got the filter sensitivity set to 3, which is the middle of the road between the lenient and aggressive ends. I would've thought that was okay. I've just bumped it up to 4 for my own account to see if that makes a difference. I don't want to get too aggressive, though...

Here's a typical example: [cid:image001.png@01CA5264.0E618600] Note that only 2 messages were blocked outright as spam, while a couple of thousand were quarantined. When I look at the quarantined messages, they're very blatant spam--various colon cleansers and enlargers and what not. I've been working with Postini support, but am going around in circles with them. They say everything is configured correctly, and they say something about them making some changes on their end, and something else about me submitting spam headers to them, blah bah. Nobody there seems to think this is quite as problematic as I do. And granted, the junk isn't making it into my users' inboxes-but it's making it into their quarantine, and it takes time to look over that (my personal daily quarantine summary generally has 150 or so messages in it). So I'm wondering of those of you who use Postini... Do you see similar results? Or do you have better luck having spam blocked outright?
