Hi,

well i believe it is possible but you need to create a work around as following;

Setting up the linux mail server as the mail smart host for the domain "egdomain.domain.com" and share the namspace with the linux mail server.

So if you configure a send connector on the exchange for the namespace "egdomain.domain.com", add the linux mail server as the smart host and mail will be sent through that both to the external users and also to clients whose mailboxes reside on the linux server.

1. Configure an accepted domain on the exchange server with the same namespace as the one on the Linux box. for e.g the accepted domain/namespace would be "domain.com",  i.e configure user1@domain.com on the exchange and user2@domain.com on the Linux box and test emails flow. you need to configure a send connector on the exchange with the namespace "domain.com" and have the Linux mail server as the smart host for that send connector. label this send connector as "LAN connector". then  setup a 2nd send connector and put the namespace as "*" and labelled it as "Internet connector".

this setup works as follows, if a user sends an email to the "domain.com" namespace and their mailbox resides on the exchange box, the EX server checks if the recipient is on that server and if not it will forward it to the Linux server since its the smart host for that namespace. if the email is not part of the "domain.com" namespace then it is forwarded outside the LAN using the Internet send connector.

2. the Linux mail server is setup to use exchange as the smarthost for the "domain.com" namespace as how the exchange send connector is setup.

I hope this will help.

Regards,
Waddah
