Here's a verbose form:
# Get an email.
my $email = get_some_email_mime();
# Get the header -- the (unfolded) raw bytes.
my $cc_hdr = $email->header_raw('Original-CC');
# parse it into an object
my $cc_obj = parse_mailboxes( $cc_obj );
# put that object into the header:
# get the raw mime-encoded bytes again:
my $cc_hdr2 = $email->header_raw('Original-CC');
# get a list of sub-object from the object's imaginary interface:
my @boxes = $email->header_obj('Original-CC')->boxes;
