Exchange 2003 Set-up Guide

Last Updated: Sep 16, 2013 03:42PM BST
This article explains how to configure Exchange Server 2003 to work with mkryptor. It is assumed that you have already installed and configured the mkryptor service. There are lots of different methods of getting Exchange 2003 to talk to mkryptor, this article details the method that we find to be the simplest.



To configure Exchange 2003 to talk to mkryptor, you need to do the following:
  1. Disable Rich-Text message format
  2. Set default Send Connector to route messages through the mkryptor service

1. Disable Rich-Text message format

mkryptor, like many mail clients and servers will not read the Microsoft Rich-Text format. It is always best-practice  to use the HTML format for internet messages. If you have not already done so, follow the below steps to disable rich-text format messages:

  • Open Exchange System Manager
  • Expand the tree to Global Settings->Internet Message Format

Internet Message Format in Exchange 2003
  • Double-click the 'Default' entry in the right-hand pane, to open its properties
  • In the properties dialogue, select the 'Advanced Tab'

Default message format properties
  • Under 'Exchange rich-text format, select the 'Never use' radio button.
  • Click OK to save the change

2. Set default Send Connector to route messages to mkryptor service

Note: This guide assumes that mkryptor is running on a separate server to Exchange. If mkryptor is running on the same server as Exchange , see the article 'Running mkryptor on same server as Exchange 2003'
  • Open Exchange System Manager
  • Expand the tree to Connectors.

Select default send connector
Note: You may have several SMTP connectors configured in your exchange environment. We are only interested in the send connector(s) for the default route (has an address space of *)
  • Right-click on your default SMTP connector and click 'Properties' to open the send connector properties dialogue

Send Connector General - DNS
  • Select the radio-button labeled 'Forward all mail through this connector to the following smart hosts
  • In the text-box, enter the IP address or host name of your mkryptor server.
    • IP addresses should be surrounded by square brackets, e.g., [].
    • If you have multiple mkryptor servers (for redundancy), enter the address/FQDN of each one, seperated by a semi-colon (;). E.g., host1.local;host2.local

Send connector properties smart host
  • Press OK to save the changes.
  • It sometimes takes a few minutes for Exchange to update its routes, so you may find that messages do not start going via mkryptor immediately
