exim4-daemon-light 4.60-3ubuntu2 (amd64 binary) in ubuntu dapper

 Exim (v4) is a mail transport agent. This package contains the exim4
 daemon with only basic features enabled. It works well with the
 standard setups that are provided by Debian and includes support for
 TLS encryption and the dlopen patch to allow dynamic loading of a
 local_scan function.
 .
 Information about the way Debian has built the binary packages is
 obtainable in /usr/share/doc/exim4-base/README.Debian.gz, and the
 very extensive upstream documentation is shipped in
 /usr/share/doc/exim4-base/spec.txt.gz. To repeat the
 debconf-driven configuration process in a standard setup,
 invoke dpkg-reconfigure exim4-config. There is a Debian-centered
 mailing list, pkg-exim4-users@lists.alioth.debian.org. Please ask
 Debian-specific questions there, and only write to the upstream
 exim-users mailing list if you are sure that your question is not
 Debian-specific. You can find the subscription web page on
 http://lists.alioth.debian.org/mailman/listinfo/pkg-exim4-users
 .
 exim is a drop-in replacement for sendmail/mailq/rsmtp.
