Hi I have an Exchange 2003 Server. I need to forward emails for an eixting user to another email address.
I have created a contact in Active Directory with the new email address and set the users account to forward emails to this contact. The cntact address is a different domain.
I am getting a error "#5.5.0 smtp;550 Relaying not allowed [id:HSWC6TD894WNP]> #SMTP#" on the forwarding.
How do I get around this without making my server an open relay?
