Hi.
I'll bring it all together here, in the meantime i have subscribed
my poor I to Ubuntu, too...

Yes, sorry, that was a typo, it is smime-xy.

and

That seems to be a very tough problem, then. ^.^

That is quite funny, indeed yesterday evening i thought about
extending the test and adding calls to openssl itself, i.e., the
command line application. We don't do much, Gunnar Ritter, the
original author, practically followed 1:1 the popular book on
OpenSSL programming ("Network Security with OpenSSL", Pravir
Chandra, Matt Messier, John Viega, O'Reilly, ISBN 0-596-00270-X).
But you will find that using the command line application just
works fine on S/MIME mails generated by S-nail, e.g.,
< ENCRYPTED-FILE
openssl smime -decrypt -inkey tkey.pem |
openssl smime -verify -CAfile TRUSTED-FILE-STORE
But i have extended the test and credited you for that:
