I have the following "problem".
I want to use an e-mail address on one exchange account as default "send" address. This address should not be accepted as domain for this Exchange server since all other accounts are on another server.
I have 3 servers running an e-mail server for this domain.
Server 1: someother mailserver also main server wich is recieving the mails and also functions as pop3/SMTP
Server 2: Backup relay server. This is only if server 1 fails the mails will still be recieved.
Server 3: Exchange 2007. This machine does is not in the MX records nor are there any other addresses from that domain on this server.
All servers are physicly on another location, and are not member of eachothers domain (Server 1 is not in a domain as we speak nor is going to run an exchange server).
What is the best solution for this, or what is the best method to implement this.
Also pelase tell me if this would not be possible at all.
