Significantly more mails quarantined with 8.200 SMTP proxy

MarCow
I'm using the latest 8.200 soft release as a software appliance install on an ASG 220.  Since the upgrade, I'm seeing 2-3 times more legitimate mail being quarantined compared to 8.103.  As one example, notification emails from nytdirect@nytimes.com were never quarantined by 8.103, but are always quarantined by 8.200.  I didn't see anything in the release notes that suggested a major revamp of the anti-spam SMTP filtering, but maybe I missed something?  I realize I could add all the exceptions into the proxy, but this could be quite time-consuming.  Also, selecting "Release and report as false positive" doesn't appear to allow emails from that same address through next time around, but I could just be misunderstanding the meaning of that option.

Anyone else seeing the same thing?

Best regards,
Martin.

    I already had Confirmed Spam being rejected at SMTP time, and as an experiment have just turned the "Spam action" option under Spam Filter to "Off" instead of "Spam", leaving the "Confirmed Spam action" set to Quarantine as before.  I'll see what effect this has.

    Even so, as Bob points out this implies a different meaning for these options that in the prior version.  Does the "Spam" option *only* include bulk mail?  If so, maybe having a "Bulk Mail action" setting would be more accurate.  If it encompasses bulk mail as well as probably (but unconfirmed) spam, then it would seem we have one config option in 8.200 where we should really have two; one of unconfirmed spam and another for bulk mail.

    Yep, sounds like we need another option or 2 for configuring the new anti-spam engine...
