Trouble Digitaly Signing Email

Asked by Autumn Lord

I own a current digital signature from Verisign. It is specifically purchased for signing and encryption of email. I have uploaded into the Preferences/Certificates and does show up and recognizes the certificate. I have approved the signing authority under the authority tab. I have went into my account listed in the same Preferences box and have added it to both S/MIME signature and encryption. I can encrypt email just fine and the encryption does work but I cannot sign any email at all. I get the following error message when I attempt to sign:

                                             Could not create message.

Because "Cannot add SMIMEEncKeyPrefs attribute", you may need to select different mail options.

Any help would be greatly appreciated. Im a MCSE that has fell in love with Ubuntu and Linux in itself but I have VERY limited skills with the application. Thank you.

Try going to edit-->preferences-->certificates-->authorities, choosing the authority that've signed your certificate, clicking edit and enabling "Trust this CA to identify mail users."

That's just an advice from some blog, so i'm not sure if it'll work in your case :)

Gnome.org's Bug 273233 or lp#41602 state that it is user behavior and a bad message, however, even when marking all 3 trust levels for my 3 CA's Certificates (organisation's certificate (issued bye someone else), then the CA, then the email-root certificate), s/mime does not work.

When I delete all three certificates, close evolution and then re-open it, it shows me neither the two of my ca's nor the one from extern, but when importing those again he complains that the extern one is already installed and is set back to untrusted.

it feels like i have two time the certificate in the store, so one is trusted and one is hidden and not trusted (ids, hash table, something with reference?

I'm adding this to lp bug, because trusting all 3 CA-Certs does not help me.

I had this problem which reproduced just as shown above, and searched around for an hour before I found the fix. Ensure that the Certificate is imported correctly - it will shown the type as Encrypt. D not worry about this - spend 30 minutes googlinjg to no effect. So I dug a little deeper in Evolution and lo and behold. - go to edit Preferences and then select Mail Accounts Select the account. Select Edit and go to the Security Tab and ensure that the Certificate is defined in the Signing Certificate field.
Problem fixed.
