Take the 2-minute tour ×  I have a mail server that scans
inbound email messages with SpamAssassin before passing messages
to Exchange 2003. When a message is considered spam, it is
marked with a certain header. Is there a way to have Exchange
2003 automatically put these messages in each user's junk mail
folder based on the existence of this header?  I realize I could
add an Outlook rule for every user. I also realize that this
rule would actually be implemented server-side. Adding a rule
for every user seems hard to implement/maintain. Is there a way
to add a global rule that works on all mailboxes?  From this
question, it looks like Exchange 2007 has something called
transport rules. Is there a way to get similar behavior in
Exchange 2003?  share|improve this question  2 Answers 2  up
