Steps to reproduce:

Create a user certificate with Novell's certificate server, set expiration date to maximum.
Import user certificate into gw8 client
create a signed message and send to another user

When the user opens that email, the client will state that the certificate is expired.

Open the same email in the gw7.03 client. The only notification is that the certificate is coming from an untrusted CA.

As medicare is started to require encryption from many entities, this is not good.
