LDN - Luminis Developer Network

Has anyone had trouble with the Sun Mail Server upgrade at the end of the 4.0.2.0 upgrade. Applying the upgrade has broken the Email Server. I think, but am not sure, that mail is still being delivered; however, SSO gives me a login screen. We are using ComExp for the mail and calendar UI. The cp.log only shows:

[2008-05-05 14:51:41,057] [ERROR](SecureRedirector.java:310) {http-80-Processor2
