Answer / olajide ilemobola

yes test1@hcl.com can send mail to test2@ibm.com using OWA
or OUTLOOK, because their IP Address are of the private
class (isolated for the public internat) and it is being NAT
(ed)to the internetusing their public IP Address

Answer / shaikh

If both the Domains are in same forest no issue test1 user
can send mail to test 2 user. If they in different forest
you should have a public DNS in place and MX record of both
exchange server should be created in public DNS.

Answer / shiv

Answer: In sufficient data.

HCL.com and IBM.com are two disparate domains. They do not
follow a naming hierarchy to look like two child domains of
a parent or neither a child or parent domain.

In this case, assumin that both are two different domains,
both will also be two different exchange organizations. So
mail would not flow just like between these two domains
before any further configuration is done.

Answer / dhananjay

both are not a same domain. if bot are not a same domain
then ip doesn't matter. if you are sending a mail from hcl
then they will go out through forwarder then it will serch
for new domain so in simple way it will go to ibm

mail

We have to create a connector between them. Either Partner or Custom connector.

Answer / alok kumar

send mail to each other if both are having trust relationshp
and also should be connected with connector

SMTP Routing in Exchange 2010 (Part 2)

The complete architecture of SMTP message processing is called the "Transport Pipeline" and includes everything that covers SMTP messages, from Send and Receive Connectors to Queues and Retention Policies.

Introduction

In Part I of this series I explained how SMTP messages are processed with an Exchange Server, in particular how a Hub Transport Server processes messages from a Mailbox Server.



Figure 1: The SMTP "Transport Pipeline" in Exchange Server 2010

I already explained how a Hub Transport Server picks up a message from the Mailbox Server to process it. There can be multiple Hub Transport Servers in an Active Directory site.

The Mail Submissions Service on the Exchange 2010 Mailbox Server notifies the Hub Transport Server that a message is in the Outbox. The Store Driver on the Hub Transport Server retrieves the message from the Mailbox Server. RPC is used for communication between the Hub and the Mailbox Server.

After retrieval, the message is stored in the Submission Queue waiting for further processing. The Categorizer picks up the message again and determines where to send it:

As it External domain To the outside world. For sending messages to the outside world (i.e. the Internet) SMTP is used as well.
