Exim is a message transfer agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet. It is freely available under the terms of the GNU General Public Licence. In style it is similar to Smail 3, but its facilities are more general. There is a great deal of flexibility in the way mail can be routed, and there are extensive facilities for checking incoming mail. Exim can be installed in place of sendmail, although the configuration of exim is quite different to that of sendmail.
An expanded, although outdated, introduction is available.
Current Exim versions are 3.36 and 4.14, both of which are bug fix releases over the previous versions.
The University of Cambridge Computing Service is hosting a fifth course on the Exim mail transfer agent on Monday 30 June to Wednesday 2 July 2003 in Robinson College, Cambridge. The course is suitable for those new to Exim as well as more experienced users. In addition to Dr Philip Hazel, there will be two external speakers.
The new book covering Exim 4 is currrently at the printers. See the book website for further information.
The O'Reilly Exim 3 book is still available.
