[Soren sent me the message off-list].

AFAICT, the S/MIME message is broken.  At least parsing it with the  
current version of openssl on my system (which should be the same  
version used internally by PHP):

slusarz at bigworm % openssl version
OpenSSL 1.0.1f 6 Jan 2014
slusarz at bigworm % openssl smime -verify < /tmp/smime.test

We are 100% reliant on PHP/OpenSSL for S/MIME parsing, so there's not  
much more we can do from a Horde standpoint.  I recommend filing a bug  
report with the program that created that message.
