s/mime not digitally signing

Hello,

I have this strange problem there Thunderbird simply doesn't sign or encrypt. I have added my s/mime comodo certificate to thunderbird, i have verified the certificate was valid inside thunderbird.

the option to digitally sign is enabled by default digitally encrypt is set to "never" by default.

now when i send out emails they do not contain any certificate. So it appears thunderbird is simply not digitally signing at all.

I am using thunderbird from Ubuntu, i do not know if i need to do anything with security devices ( i left this default).

Any help about this issue will be much appreciated.

Regards, Marco

all you see in Thunderbird for digitally signed mail is an icon in the mail header. an envelope with a red spot on it. No attachment. Same with most mail clients that understand s/mime. Usually only those that don't understand s/mime show the attachment because they don't know what it is.

hmm normally atleast in outlook it clearly shows you have a s/mime certificate.

I checked in both OWA and Outlook after sending a mail to my self from TB --> nothing showed.

If i chose to encrypt i can still read it on my mobile that doesn't have s/mime support (didn't enable the extra plugin for android there), if i do the same with my outlook s/mime it: 1) becomes unreadable after encryption on devices that do not support s/mime 2) shows a certificate icon

So in all accounts i am pretty sure my TB doesn't do anything with s/mime. I actually seen similar complaints in the original addon before it was integrated in TB it self.
