-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.

+		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.
