I am new to the administration Zimbra and SPAM Assassin and I am having trouble tracking down a problem. This started a week ago and appears to be random. We are having email ending up in the junk folder that has a score below the spam threshold. I was wondering if anyone had any suggestions on what to look for as far as configurations.

Below are a couple headers including the one from my registration for this Zimbra board that ended up in my junk folder this morning.
