I would suggest that you scan and tag all incoming messages. Don't make any subject or body changes, just let SA add the headers. Then your global procmailrc can drop the high-scoring spam and your users .procmailrc can use the same headers for further processing if they want to sort out the spam or drop more of it. This way the headers are always there and the users can either take advantage of the spam scan or ignore the headers. Bowie
