733518 - Unable to send signed email with valid certificates

Status: RESOLVED WORKSFORME

(MailNews Core :: Security: S/MIME, defect)

Description

[Nicola Ferralis]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:10.0.2) Gecko/20100101 Firefox/10.0.2
Build ID: 20120215223356

Steps to reproduce:

I am trying to send signed emails using valid certificates (both personal and root from my employer) and every time I try that I get the message:

"Sending of message failed.
Unable to sign message. Please check that the certificates specified in Mail & Newsgroups Account Settings for this mail account are valid and trusted." 

I had this problem since TB5 (possibly even before then) and it still persists to 10.0.2. The issue is present in TB for OS X and Windows (I haven't tried Linux). Using a clean profile doesn't fix the problem, as well as making new certificates. These certificates work perfectly well in FF when used to access my employer restricted websites as well as when used to sign emails with Apple Mail.

Actual results:

Upon any attempt to send a signed email, I receive this error message:

"Sending of message failed.
Unable to sign message. Please check that the certificates specified in Mail & Newsgroups Account Settings for this mail account are valid and trusted." 

The email is not sent.



Expected results:

The email should have been sent, signed.

The bug is present also on a clean profile with TB12a2.

Also, if I send a signed email to myself, and I "view the security info", I see that the panel that opens up doesn't show any valid certificate, although one is clearly installed. 

The error console doesn't show any error.

I had that once or twice and even filled a bug about it. But I never was able to reproduce.

Are you offline when this happens ?

This bug is still there! Fresh installation of 28.0.1 has this bug.

I have also imported the intermediate CA, still no luck.

Although this is an very old report - the bug is still present on a new installation of Thunderbird 68.2.2 on macOS 10.15 - S/MIME signed mails can't be send. Hopefully it will get fixed soon - it prevents me from using Thunderbrid.

It certainly works in general (I just tried it). If it doesn't work, make sure the certificate is correct in all ways.
Closing this since it's an old bug. Any new issues should be filed as such.
