I'm having trouble understanding why when the following code is executed, only the last item in the DATA appears in the hash. 

#!/usr/bin/perl

use strict;
use warnings;

use Data::Dumper::Simple;

my @array;
my %hash;

while(<DATA>){
  chomp;
  @array = split /\s+\s+/, $_;
  %hash = ($array[0] => {$array[1] => $array[2]});
}

print Dumper (%hash);

When executed, only the last item appears in the hash. 

%hash = (
          'employment' => {
                            'LifeShopDirect@freshcornam.com' => 'Host 
+not found'
                          }
        );

Thanks,

Update I: I just realized that @array only had three items in it, which is of course why the HoH only has the last item in it. If there's a better way to approach this, I would appreciate comments.
Update II: Thanks very much for all the comments. I believe I have a workable solution now. Thanks very much to all. I will test each method and try to understand each one.
