I have been working with exchange and perl for a couple of years now and I've learned at least one thing: It ain't easy!! But I'm sure you will find that out for yourself if you haven't already. Now that I've gotten that out of the way, try this on for an example: 
#!c:\perl\bin\perl.exe -w

use strict;
use warnings;
use diagnostics;

use Net::LDAP;

#The following will be different depending on your mail server
my $mailserver = "mail.company.com"; #internet accessible name of the 
+server
my $port = 389; #LDAP port number
my $org = "organization"; #Top level Exchange Organization (o)
my $site = "site"; #Actual exchange site

my $ldap = Net::LDAP->new($mailserver,port=>$port) or die "$@";
my @Attrs = (); # request all available attributes to be returned.

my $result = $ldap->search (
               base    => "cn=Recipients,ou=$site,o=$org",
               scope   => "sub",
               filter  => "cn=*",
               attrs   =>  \@Attrs
               );

my @entries = $result->entries;

foreach my $entr ( @entries )
{
    print "DisplayName: ",$entr->get_value('cn'),"\n";
    print "Department: ",$entr->get_value('department'),"\n";
    print "Email: ",$entr->get_value('mail'),"\n";
    print "#-------------------------------\n";
}

$ldap->unbind();
exit;

Update:
I got this to work on both win2K and linux.
