I have Microsoft exchange 2003 organization with a number of routing groups and connectors created.
I need to forward all emails sent from one certain email address (firstname.lastname@example.org) which is in our exchange organization sent to domain (subdomain. domain.co.uk)) which is not part of our exchange organization but can be if needed to an another internal IIS server.
The way I thought I would do this is create a connector on exchange with a lower address space cost than our primary connector and under “Forward all mail through this connector to following smart hosts” type in the host I want to forward to and thought that would work but it does not.
I can see that the policy of the connector is working i.e. it is defiantly trying to forward the mail from the newly created connector but keeps failing with a 4.3.2 error.
I have tried telnet on port 25 to the IIS server from the exchange server and sent a mail using telnet successfully so I know telnet on port 25 is working.
Could someone please help me or let me know off another way of doing this?
