exim4_30 with TLS

Hi
 
Has anyone experience using GNU JavaMail and EXIM Mailserver 4.30

Our Mailserver is configured to using TLS and i try to write a client 
for this. The first thing i did, was to add additonal code into the
starttls() method, because the original method only proceeds if 250 OK 
is returned, but Exim returns 220.

This did not help.
Exim is throwing stll : 550 authentication required.
What i ensured is, that no SASL Client could be established

regards

Michael
