We have one user that gets a lot of SPAM that is being detected but not rejected due to its score. The same message has been sent to 5 users. For 4 users the score is high enough that the message is rejected. For the 5th user the score is only high enough to have it detected.

> Are the "detect" and "reject" thresholds global (server or domain wide) or for each individual user? It the latter where do I set it?

Email headers in email message source.

I have had this exact same thing before. The issue was that the low-score spams were actually sent through a different mail server than the high-score spams. As Pavel said, you need to compare the mail headers to see the actual path of the email.

We only have one mail server. Have looked a email header for the "detected" email. Would like to see the header in the "rejected" email. Is there a way?

The "detected" emails all went to specific email addresses on the server. The "rejected" email was to a mail group that had only a single member.

I wasn't referring to your email server, I was referring to the sending or intermediate email server. For example, the exact same email sent from Server A is detected because it is known to send spam, but the not-detect email sent from Server B goes through because that email server is not on any black lists yet.

Thank you. Sorry that I didn't understand. I will look at how the email was routed from the sender to our server.
