I want all inbound and outbound e-mails to go through a smart host; I have a firewall, exchange 2003, and IronPort as a smart host. I have configured my firewall to only allow port 25 in and out through IronPort. I need to know how to configure exchange to send and receive, or for the lack of better term relay all e-mails through Iron Port. How do I setup the connection on exchange?David

You configure the outgoing smart host on the SMTP sendconnector.Incoming is configured with MX records in DNS.lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com

The below steps will help you to configure for the smart host such as forwarding all outgoing mails to your Iron Port. In the Exchange System Manager, expand the Administrative Groups container. Expand the desired administrative group, and expand the Routing Groups container. Expand the routing group you need to work with, right-click the Connectors folder, and select New. Select SMTP Connector. On the General tab, enter a name to identify the connector. Select Forward All Mail Through This Connector To The Following Smart Hosts, and enter the IP address of the other site's mail server, enclosed in brackets (e.g., [172.25.3.110]). Under Local Bridgeheads, click Add, and select the SMTP server that will become the SMTP bridgehead for its routing group. On the Address Space tab, click Add, select SMTP, and click OK. In the E-Mail Domain box, add the name of the remote location's e-mail domain (e.g., domain.com), and click OK. On the Advanced tab, select Outbound Security, and select the proper authentication method for your relay host. Anonymous Access is the default. Click OK three times to exit the SMTP connector configuration. Restart the Microsoft Exchange Routing Engine service and the SMTP service. For recving emails via Ironport you need to Point your MX record to ironport host. Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi David, For outgoing settings, we need to create a smtp connector, Vinod had provided the steps in detail. For incoming settings, your recipient policies must be configured correctly, you must configure a recipient policy that contains an address space matching the SMTP domain. Also, your Exchange organization must be responsible for delivering mail to this address (this is the default setting). For example, to accept Internet mail for ted@example.com, you must have a recipient policy that contains @example.com.
