Download the latest released Mail Toaster.
mkdir -p /usr/local/src cd /usr/local/src fetch http://mail-toaster.org/Mail-Toaster.tar.gz
Once downloaded, extract the archive and install it much like you would any other perl module.
tar -xzf Mail-Toaster.tar.gz cd Mail-Toaster-N-NN perl Makefile.PL make deps ** make test make install ** 'make deps' is helpful but not required.
Note: It's ok if a few tests fail. Once your toaster is fully installed, you can run "make test" and it will run quite a few more tests and should succeed with no errors.
Documentation for the modules being called by toaster_setup.pl, toaster_watcher.pl, maillogs, and index.cgi are all installed in Perl's pod format (perldoc Mail::Toaster) as well as being available online.
