I have a lovely little Java client that sends signed email messages. We have an Exchange server that requires username/password authentication to send a message. When I connect to the exchange server, I get this error: avax.mail.AuthenticationFailedException: failed to connect at javax.mail.Service.connect(Service.java:322) at javax.mail.Service.connect(Service.java:172) When I connect to other servers (Unix servers), I have no problem.
