Same email but two different spam scores

[bquinata]

Received a company-wide email which arrived in my Inbox just fine, but a co-worker found that same email in her Junk folder. She was the actual sender and it went to a distribution list which we are both on.

Here are extracts of both of our headers:

X-Spam-Flag: YES
X-Spam-Score: 6.681
X-Spam-Level: ******
X-Spam-Status: Yes, score=6.681 tagged_above=-10 required=6.6
tests=[BAYES_80=2, HTML_MESSAGE=0.001, RCVD_IN_PBL=0.905,
RCVD_IN_RP_RNBL=1.31, RCVD_IN_SORBS_DUL=0.001, SPF_PASS=-0.001,
T_RP_MATCHES_RCVD=-0.01, URI_OBFU_WWW=2.475] autolearn=no

Where was the message originally received from? Those two spam scores are different with regards to: RCVD_IN_PBL=0.905,
RCVD_IN_RP_RNBL=1.31, RCVD_IN_SORBS_DUL being only in the first one. Most likely, the message came through from two different paths.

I would be curious to see the received headers for the two messages.
