	email_sep = re.compile(r'\s*,\s*')
	if 'Reply-To' in msg['headers']:
	senders.append(msg['headers']['Reply-To'])
	elif 'From' in msg['headers']:
	senders.append(msg["headers"]["From"])
	if 'To' in msg['headers']:
	recipients += email_sep.split(msg['headers']['To'])
	if 'Cc' in msg['headers']:
	recipients += email_sep.split(msg['headers']['Cc'])

a mail with a To: "Lastname, Firstname" <first.last@example.org> causes the reply to have

To: "Lastname
Cc: Firstname" <first.last@example.org>
