Okay, I am really starting to show some wear on this one...so please, HELP!
I have exchange 2003 running IMF. My clients are all OWA 2003 or Outlook 2003 (cached). Gateway Threshold is 6 and move to Junk is 3.
I am getting spammed and the sender/reply address is a spoofed address from our domain. Despite IMF assigning the message an SCL rating of 5 Outlook seems to place these messages in user's Inboxes. Now, the interesting thing is, is that Outlook is not doing this consistently. Sometimes it moves the messages to Junk but other times it doesn't. I have no idea why it's doing this, but some insight would be great!!
