HOWTO: Programming S/MIME in Python with M2Crypto

[Graeme Longman]

Hi,

>From my understanding you don't need to make any changes to Outlook to
receive digitally signed mail.

I have been using your your HOWTO to generate the certificates and the mime
string of the signature. I have also managed to get the example, Sending
S/MIME messages via SMTP, working with Outlook. I can't seem to get the
earlier examples working though. I have tried fiddling with the mime string
before sending it via SMTP but haven't had much luck. The same error
message, "Can't open this item. An error occured in the underlying security
system" always seems to 'pop-up', even though the actual mime of the email
seems to correspond exactly to a working example.

I know that in the HOWTO you don't actually send the example in 'Sign' but
have you managed to send and receive this example. If you have successfully
then maybe it is the 'Outlook' issue.

Thanks for the help,

Graeme

Whoops, replied on Usenet before I saw this.

Essentially, I've never tested M2Crypto.SMIME with Outlook. If you can show
me how to set up Outlook with keys and certs, I'll give it a go.

Cheers.
