When programming in undetermined environments you have to be constantly
aware that things may not be what you expect.  In this case: messages
may not be in a correct format.

As others already stated, undef is a useful return.  I have the choice of,
either write
   my $from = $head->get('From') or return;  # or exit, or next
   my $from = $head->get('From') || '';      # set default
Best would be
   my $from = $head->get('From') // '';
But that requires perl 5.9 or Merijn's 'err' patch.

In this specific case, you could also do:
  my @from = $msg->from;

This is all common Perl (you will have these options/problems in all
Perl programs) and is therefore not included in the MailBox documentation.
Although... I could include some examples with these trics anyway...
