Here is my take:


#!/usr/bin/env perl
use warnings;
use strict;
my %EMAILS;
while (<>) {
    if (/([a-z0-9.-]+\@[a-z0-9.-]+)/i) {
        if ( !defined( $EMAILS{$1} ) ) {
            $EMAILS{$1} = 1;
        }
        else { next; }
    }
    else { next; }
}
foreach my $addr ( sort keys %EMAILS ) {
    print "$addr\n";
}
