I was able to do a "Save Keystore As".
Unfortunately, I cannot give you the keystore for
testing since the private key is still in use, but this
keystore-report may give you some evidence on what type
of key we are dealing with:

didn't work either with sun's keytool:

$JAVA_HOME/bin/keytool.exe
-keyclone -alias smtp.privasphere.com -dest
new -keypass changeit -new changeit -storetype JKS
-keystore james.ks
-storepass changeit -v
keytool error: java.security.UnrecoverableKeyException:
Cannot recover key

I created the keystore with jdk 1.4 and now I am trying to
decrypt it with jdk1.5

or could it be that the key password is wrong...

Sorry for the delay, I thought email notifications for
sf.net tracker items were enabled, but turns out they
were not.

It looks like the validity period of the certificate has
passed now. In case you still have it around, could you
send it to me for testing? (Private mail is ok too.)
