Hi All:


We have a domain 'abc.com' hosted on Linux Sendmail System. We are trying
migrate some of the users from the Linux System on to an Exchange 2003
Server. The users which will be migrated will use the same Outgoing Domain
i.e. 'abc.com'. The mail from the Internet will first hit the MX Server (In
this case the Linux Server) which will be then forwarded to the Exchange
Server using an IP Forwarding. We have configured the users on the Exchange
Server with same SMTP domain as 'abc.com'. The mail flow from Linux to
Exchange Servers is working fine. However whenever we trying to send a mail
from Exchange Server to the users on the Linux Servers using the same domain
name 'abc.com' it throws an error the 'User does not exists in the
Organization'. We have already created an SMTP Connector on Exchange Server
for the address space 'abc.com' and using Linux server IP as the Smart Host.
However this doesn't work. Can anybody help us on the same or the finesse of
SMTP Connector.
