Mail::Header

• Mail::Header is loaded by Mail::Internet

• Let's see where Mail::Internet is used:

        sub handle_message {
          my $message = $_[0];
          my $mi = Mail::Internet->new($message);

          $count++;
          $total_size += length $mi->as_string;
          letter_histogram( $mi->as_string );
          from_histogram( $mi->head->get("From:") );
        }

• It would appear that it is being used to:

  1. Convert the message to an object and then back to a string, and

  2. to extract the From header
