exim4 4.60-3 (i386 binary) in ubuntu dapper

metapackage to ease exim MTA (v4) installation
 Exim (v4) is a mail transport agent. exim4 is the metapackage depending
 on the essential components for a basic exim4 installation.
 .
 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.
