Outlook Express can't recognize my encrypted mail?

hi all,

	I encounter some probelm when I try to generate a encrypted mail.
I use the tool "mimetest" to do the job. You can see the .cfg files 
that I use at the end of this mail. All the necessary cer files and
data files are put in the subdir ./tuzi. By running 
"mimetest mimetest.cfg", I can generate a eml file named ./tuzi/tuziEncrypted.eml.

I tested this file with a small tool written by SFL (I wrote it myself). This mail
 can be decrypted correctly. But when I try to read it with Outlook Express (OE), it failed.
So I generated another encrypted mail by OE, which can also be decrypted by my tool.
It is obvious that my small tool works well. And I am sure that I have imported the
corresponding certificates into OE, and this is not due to the dos2unix/unix2dos file
format problem (all my programs run on a solaris).

So, how to generate a OE compatible encrypted mail with SFL?

Thanks all, I really appericiate your help.
