In one of your responses to a question regarding Microsoft Exchange, you made the remark, "Ensure that your message...
transit agents (MTAs) are sufficiently configured to NOT allow spam or mail-relaying." I would like to configure this, but when I went into the configuration in Exchange Administrator, I could not find MTA. Could you please tell me where it is located and how to do this configuration? We have Exchange 5.5.
- In the Exchange 5.5 Administrator, go to Configuration/Connections/Internet Mail Service.
- On the Routing tab, click on "Routing Restrictions."
- Under "Specify the hosts and clients that can route mail when the following conditions are met," place a check-mark next to "Hosts that successfully authenticate."
This will preclude a third party using your mail server for indiscriminate mail and spam relaying.
