Any SMTP server will queue the mail for you automatically. That's built-in to the protocol.
I'm not sure I understand what you're looking for...it sounds like you are looking for a SMTP server written in Java. There are plenty of free, open source SMTP mailers out there, but if you need it in Java, that would be the JavaMail API: http://java.sun.com/products/javamail/, most likely com.sun.mail.SMTPTransport.sendMessage(Message message, Address[] addresses). I don't think JavaMail offers any queueing or redundancy, but you can use a simple database operation...insert a record just before the message is sent, send the message, and trap any exceptions. If no exceptions, mark the new record as "sent". Periodically, have a process look in the database for records that have an exception, then attempt to resend them, assuming the logged exception is "server down" and not "user unknown" or something else that would prohibit the email from being sent.
