Yeah, in a modern Perl that's provided by the cpan(1) command (older
versions of Perl traditionally used a one-liner that used the standard
CPAN module).

Nevertheless in that page there's a script, and documented
dependencies, and it is not packaged as a distribution avaliable from
CPAN, so you need to install all modules listed in the dependencies
section like this:

   sudo cpan Email::Outlook::Message
   sudo cpan Email::LocalDelivery
   ...

Some of them are already in your machine but running cpan(1) on them
won't hurt. First time you run cpan(1) you'll get some questions.
Defaults are fine, and as for mirrors choose whatever it's close to
you.
