Message transfer agent for Unix systems

Exim is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet. It was originally based on Smail3, and has a similar configuration style, but has developed a more flexible and extensive set of facilities. The developers warn that v. 4.00 has had many changes, including incompatible changes to the run time configuration file.
