Ok, here is the head of one of these mails that were marked as spam although the address is in the whitelist of the receiver:
I think I know why the mail is marked as spam (one of the reasons should be the X-Originating-IP is on a blacklist) but this is not my point.

X-Mailer: Microsoft Outlook 14.0
X-Mailer: Zimbra 6.0.10_GA_2692 (ZimbraConnectorForOutlook/6.0.6058.8)
This is a multipart message in MIME format.
I can't see something in this header that looks like the whitelist was checked.
Can anyone tell me what is written in the header when a message was whitelisted?
Oh, and another question by the way: The sender and the receiver are using the same mail-server. They both are conntected via zimbra outlook connector with this server. Besides the whitelist am I wrong or shouldn't be the "ALL_TRUSTED=-5" of my configuration also in the list of spam-tests above? Or is this test made with the "X-Originating-IP"?
P.S.: Sorry for my bad englisch - it's too early ;-)
