JRE 1.5 VS. JRE 1.6 - Could not convert socket to TLS

Question

I have an applet that is trying to send an email through an SMTP server. It works just fine 1.6 but on 1.5 it blows up and I'm kind of at the end of my rope. Any help here would be great.
I've had to set up the DummySSLSocketFactory as described in the JavaMail readme but still no luck on 1.5.
Here is the error:
DEBUG: setDebug: JavaMail version 1.4ea
