exim4-config 4.60-3ubuntu2 (i386 binary) in ubuntu dapper

 Exim (v4) is a mail transport agent. exim4-config provides the configuration
 for the exim4 daemon packages. The configuration framework has been split
 off the main package to allow sites to replace the configuration scheme
 with their own without having to change the actual exim4 packages.
 .
 Sites with special configuration needs (having a lot of identically
 configured machines for example) can use this to distribute their own
 custom configuration via the packaging system, using the magic
 available with dpkg's conffile handling, without having to do local
 changes on all of these machines.
 .
 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.
