User whitelist not working as expected

I have 2 scenario's where I want PMG to treat a message as spam.

1. If the SpamAssassin score is >= 5
2. If my upstream filter has already prepended the subject with "SPAM"

I have rules to accomplish this, and it works fine. However, the user whitelist isn't working as expected for me.

My mail filter rules are:

  • What = Spam level 5
  • Action = Modify Spam Subject; Quarantine
  • What = External Tagged
    • Match field: Subject=^SPAM:
  • Action = Quarantine

In case #1, I send an email from an email that is whitelisted by the recipient. PMG recognises this and even though the SA score is >= 5, it continues to deliver the message onwards. This is what I expect to happen.

In case #2, I send the same email but prepend the subject with "SPAM". PMG recognises that the sender is whitelisted by the user, but still sends the message to quarantine.

Here's the logs from the 2 attempts:

#1: Email that gets a SA score of 5

Any thoughts on why these two cases are treated differently with regards to user whitelist?
