=item 2

You also need the Perl modules C<Data::Dumper> and C<Mail::Internet>,
both available from CPAN. If they aren't installed, you can't run
C<leafmail>.

=item 3

Make sure the hash-bang line at the top of the C<leafmail> script points
to your copy of Perl. B<chmod> C<leafmail> to executable, B<chown> it
to B<mail>, and stick it in I</usr/sbin> or somewhere similar.

=item 4

Edit your copy of I<leafmail.cf>, the C<leafmail> configuration file. Put
it in I</etc> and make sure it's readable by C<leafmail> (but not writable
by non-privileged users!). Ensure that the spool directory indicated in
I<leafmail.cf> exists and is readable, writable, and executable by the
owner of the I<leafmail> program (i.e. probably the UID B<mail>).
