I'm a bit stuck right now and was hoping for some divine monk intervention so I can kind of move past this current block that been eating away @ myt brain for the past 24 hours. I'm sure the answer is simple and I'm just not "seeing it" because I'm so caught up with the entire script.

I basically need to pass a hash to a subroutine and then iterate through the hash in the subroutine and email it's contents to myself. I used the Perl Cookbook's emailing recipe (18.3) because it seemed a bit easier then invoking SendMail directly (I don't know how to do that) - where I'm stuck is how to iterate through the hash and assign it to the $body variable so the hash contents can be sent via email. I know the snippet I'm including has a scoping problem.

Is there any way I could get some answers and just a short discussion of how to implement the solution properly and a way I could avoid this in the future. I'm sure it's a design problem - that's what I get for not being a programmer.

#!/usr/local/bin/perl -w

use strict;
use Mail::Mailer;

my %hash = (

    '742+evergreen+terrace' => '60516',
    '1094+evergreen+terrace' => '60187'

    );

notify(\%hash);

sub notify {

    my $error_hash = shift;

    foreach my $address (keys %$error_hash) {
         $contents = "$address $error_hash->{$address}";
    }

    my $from = 'system@system.com';
    my $to = 'me@system.com';
    my $subject = 'Warning';
    my $body = $contents;
    
    my $mailer = Mail::Mailer->new("sendmail");
    
        $mailer->open({
           From    =>  $from,
           To      =>  $to,
           Subject =>  $subject,
       })
       or die "Can't open: $!\n";

    print $mailer $body;

    $mailer->close();

}
