#secure smime signencrypt not working to myself

[david.goldberg6@verizon.net (David S. Goldberg)]

A while back I posted my method for doing smime encryption and
signatures by building a multipart around the entire message and call
mml-secure-encrypt-smime and mml-secure-sign-smime and going through
the headers to insert the appropriate key and cert files.  The recent
changes made to gnus' smime functionality encouraged me to try to work
in a more "standard" fashion so I set up mml-encrypt-alist to use my
function to traverse the headers and determine the appropriate key and
cert files (I still haven't had much luck with the new ldap interface,
probably because I use XEmacs) without prompting when I run
mml-secure-message-encrypt-smime and it works mostly great with one
exception.  Messages either sent to my self via mail or gcc are not
readable.  I get an error: Could not identify PKCS#7 type.
Thunderbird is also unable to read the message so it's not just some
weird limitation in gnus.  On the command line I'm able to pipe
openssl smime -decrypt to openssl smime -verify to read the message.
Go figure.  mml-signencrypt-style-alist is the default with smime set
to separate, but it's apparently not equivalent to having two mode
tags in the #secure which is just as well since #secure only seems to
be willing to recognize one mode tag anyway.  Any thoughts on how to
track this down?

Thanks,
