This is unfortunate because the underlying javax.mail.Message interface does support multiple replyTo addresses.
http://download.oracle.com/javaee/6/api/javax/mail/Message.html#setReplyTo(javax.mail.Address[])
Supporting this would be a very simple addition to the API as has been done for the setCc method.

I'm afraid that we won't add any further features to MailMessage at this point, in particular not for rather uncommon scenarios. For such cases, you may use JavaMailSender with a full JavaMail MimeMessage... or simply use the JavaMail API directly.
