The paper discusses a method for removing the risks associated with
presenting Microsoft Exchange directly to the Internet. It addresses
issues for administrators who must use Exchange in a corporate
environment, but have concerns over its ability to protect the valuable
resources it holds, or its ability to provide advanced routing and
filtering of messages before delivery.
The tutorial shows a real-life example of Exim in use as an SMTP gateway
to an internal Exchange server, providing a level of separation from
Internet based enumeration tactics and exploits.
The tutorial provides a mechanism for:
* Proving temporary redirection by Domain.
* Providing permanent redirection by email address.
* Restricting the domains allowed for relay and delivery.
* Restricting IP addresses allowed for relay and delivery.
* Sending and receiving mail via a dedicated appliance or third party
Virus/Spam/Porn scanning service such as Messagelabs.
