Sometimes, Email::Simple and friends are too simple. I strongly suggest you look at Mail::Box. It looks big and complicated because of the incredibly complex class heirarchy, but read the Mail::Box::Cookbook and experiment with it and you'll find it's not terribly hard to use. Once you get used to it (and there is a big learning curve) it's a swiss-army-chainsaw for mail processing.

Given your question, you probably want something like this (not tested): 

my $manager = Mail::Box::Manager->new;
my $folder  = $manager->open( folder => $ENV{MAIL} );
foreach my $message ( $folder->messages ) {
  next if $message->label( 'seen' );
  my $bounce = $message->bounce( To => 'you@somewhere.com' );
  $bounce->send;
  $message->label( 'seen' => 1 );
}
$folder->close;

Look at Mail::Message for other things you can do with a message (reply, forward, etc.) There's also very good online documentation with links for a mailing list that is very responsive to questions.
