Hi helper: I have installed a exchange 2003 in exchange 5.5 site. is there any way that i can bypass the exchange 5.5 server without remove the exchange5.5 server? that means I like to send emails from exchange 2003 directorly to firewall and go out? at the moment the exchange 2003 uses ADC sending email out through teh exchange5.5 and I can receive emails with exchange 5.5 turned off but not send emails. Thanks for any help.
