We are using Exchange 2000 for corporate and Internet mail and actually we
know it is used for spamming.
I change the relay security option to authenticate the local computers only
and allow them to send mail through SMTP Virtual Server, but now, is not
more possible send and to receive messages, from and to anyone!!! All relay
port is closed!!!!
I know that this setting is correct (with Exchange 5.5 worked), but does the
solution to this problem exist??? it's my error or a bug of Exchange2000?
Who can help me?
