We are running Exchange 2007 and have come across an issue where nearly all our emails are being appended with "Spam:" in the subject field.
This started happening when we got back from out christmas holiday. I did learn that the exchange server went down over the holiday period and someone came in and reset the server. I'm wondering if this may have finished off installing an update of some sort and changed the settings.
I could not find any settings to change or even where to look whether it be in exchange management console or our anti-virus program, we are running Trend Micro Worry Free Business server edition. I couldn't find any settings regarding filtering emails.
This "Spam:" notice is also happening to some of our internal emails and from people we send and receive emails to and from everyday.
Here is a copy of the header of one of the emails:

If you require any more information, I will be happy to provide.
Notice: I do have a lot of experience in computer systems but not a great deal in exchange servers. I did notice the SCL is rated at -1 where i thought it could only be rated from 0-9?
