Exchange Mail Flow

Exchange Mail Flow Introduction

Once we have installed Exchange Server 2016 in the organization, it requires configuring mail flow and client access in order to send to Internet and external clients such as Microsoft Office Outlook, and Exchange ActiveSync.

Below are the steps involved in Mail flow and CAS server configuration:

Create a Send connector
Add additional accepted domains
Configure the default email address policy
Configure Internal & external URLs : will be discussed when publishing exchange
Configure an SSL certificate : has been discussed and applied previously – please back to article exchange https certificate

Send Connector

Send connector Allow Exchange server to send emails externally based on it’s the configuration

Receive Connector

Receive Connector: An inbound Receive connector will be created by default when an Exchange server 2016 is installed.

This default Receive connector accepts anonymous SMTP connections from external servers;

hence it is not required make any additional configuration for receive connector

but later we may configure SMTP relay for anonymous internal server like SharePoint and SCCM , SCOM ,,etc.

Additional accepted domain

An accepted domain is a SMTP namespace for which a Microsoft Exchange Server sends or receives emails.

To simplify point

Currently Exchange will add suffix email address for each user @pioneers.lab since we have installed exchange on Active directory pioneers.lab

For example default email for mark is mark@pioneers.lab

Of course pioneers.lab doesn’t reflect our domain which will be published to internet

For example let’s supposed we would like to use our external domain @net-pioneers.com

Then simply we will add new accepted domain name net-pioneers.lab

Let us go ….

Now .. Any new user will have email address @net-pioneers.com

But what about previously created email address …

this could be done by [ email address policy

Email Address Policy

as we mentioned above any new user will have email address suffix @net-pioneer.com ,

but regarding previously created email address > this will be Done using Email address Policy
