I've heard of the various modes that Exchange 2007 can be configured and I was wondering if anyone can point me to the right direction as to what mode is most appropriate for this scanrio.
I have a Server 2003 based network with Exchange 2003 on a front/back end configuration.
I have a new Server 2008 (64 Bits) server that I would like to install Exchange 2007 to begin moving users little by little. The front end server is doing OWA and is critical to the organization. One Exchange organization and one single domain.
Email comes first to a McAfee 3200 SCM appliance that scans for SPAM and then forwards to the front end server. I host multiple domain email address. I'll be happy to provide more ifnromation if needed. Thanks
