Hello

A couple of months ago I started to use smime, with epg, gpgsm
(certificates from comodo). I had no problems interchanging encrypted
and signed message with users of thunderbird (seamonkey), evolution,
kmail and applemail.

However I do have problems with users of outlook 2003/2010 (and these
users cannot change their mail program).

So I installed outlook 2003 in a virtualbox and indeed (after having
installed the certificates and interchange signed message) I receive the
following error message when  opening an encrypted+signed message sent
by xemacs:

"Your Digital ID name cannot be found in the underlying security system" 

So I thought this is outlook's fault. 

But then I tried out thunderbird, and outlook has no problems opening a
signed+encrypted message.

Then I tried out kmail, which also uses gpgsm, and again outlook can
open the signed+encrypted message.

So I am really puzzled. I saved the 3 messages

    -  thunderbird

    -  xemacs

    -  kmail

In thunderbird .eml format and attach them below. The difference between
kmail and xemacs is very subtle, but I fail to see any deeper reason.

Any suggestion is very welcome.

thanks
