Java APIs

Hi,

I am facing issue, connecting clients Exchange server via JAVAMAIL api using pop3. It works fine with gmail. Please look into this, if is something familiar.

Following exception we get while trying to connect on client's Exchange server


javax.mail.MessagingException: Connect failed;
nested exception is:
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connecti
on?
