Hi! I'd like to finish the thread I started. - My first statement was wrong. Also 1.0.0e is not able to process my SMIME-sample. The reason was that I had a smime-binary-patch installed at the 1.0.0e some years ago and I did not remember about it. Without the patch installed in the 1.0.1e it looks like a change in functionality between the version. - Many thanks to Dr. Stephen Henson for his help and support. This solution (parse it externally and verify it with openssl-cms) works fine. Best regards, Chris
