I have an Ex2007 gateway running CAS and Hub Transport roles. I setup a transport rule to apply a disclaimer to my outbound emails. This works fine when sending using my Ex2007 mailbox however we have all our Ex2003 servers (until they are migrated) pushing emails out from this server and all emails are being garbled. Here is an example. Test Test Disclaimer Is there a way to fix this or have Ex2007 transport rules ignore the message if it comes from a Ex2003 mailbox?
