Unless you would like to offload such things as gateway antivirus protection and content screening. Those are good applications to put on relay servers like you are talking about.

If your IMS server is a dedicated box (no mailboxes) the need for a relay server is somewhat diminished in my mind. > -----Original Message----- > From: Jonathan Beeler [mailto:[EMAIL PROTECTED]] > Sent: Monday, June 24, 2002 10:57 AM > To: Exchange Discussions > Subject: IMS routing question: > > Currently, we're running Exchange 5.5 SP4 with hotfixes on an NT4.0 SP6A > servers.
