Is it possible to send messages if some of the addresses are invalid? By default, if any addresses are invalid the message isn't sent.

John Zukowski You need to set the mail.smtp.sendpartial property to true:
props.put("mail.smtp.sendpartial", "true");By default, this is false. The partial failure will trigger a SendFailedException.
This assumes the SMTP server is setup not to fail multiple recipient mail if any address is invalid.
