Hi! I have exchange 2003 on win2003 set up as a gateway for exchange 5.5 organization. I had some problems with sending mail but when I turned-off 8bitmime support on ex2k3 server everything was working just fine. The problem is that 8bitmime support turns itself on every couple of days for no apparent reason and then the mails aren't working. Could someone tell me why is it that 8bitmime turns itself on, and how to prevent it? Thanks Damir Makovica
