Status: RESOLVED INVALID

(Thunderbird :: Untriaged, defect)

Description

Attachment: Enigmail_debug_log_20180331

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0
Build ID: 20180326161258

Steps to reproduce:

Error:
Thunderbird / Enigmail does not automatically attach Sender’s public GPG key, even though it appears to be configured to do so.  This seems to have started happening after I got the update to Enigmail 2.0.  

I have also reported this bug to Enigmail / SourceForge.

To configure Thunderbird to attach the Sender’s public PGP key I have done the following:

-In the laft pane of Thunderbird right click on the Sender email address in question
-Click on Settings in the drop-down
-In the “Account Settings” window that appears, under the Sender’s email address in question, click on OpenPGP Security
-In the right pane of the “Account Settings” window click on the “Advanced...” button
-In the “Advanced Enigmail Identity Settings” window that appears, place a check next to “Attach my public key to messages”
-Click OK in the “Advanced Enigmail Identity Settings” window
-Click OK in the “Account Settings” window

I then compose an email as I normally would:

-Highlight the “Inbox” under the Sender’s account in the left pane of Thunderbird
-Click on the “Write” menu in Thunderbird
-Type in the recipient’s address, the subject, and the body of the email
-Click SEND in the upper left of the window where I compose the email

Results:

-The Sender’s public GPG key is NOT attached

I can “manually” attach the senders public key if I do the following:

-In the window where I compose the email I click on the “Enigmail” menu
-In the drop-down I click on “Attach Public Key...”
-In the “Enigmail Key Selection” window I place a check mark next to the Sender’s key entry
-Click SEND in the “Enigmail Key Selection” window

Results:

-The Sender’s public GPG key is IS attached.  It has the format 0xBABEFACEBABEFACE.asc

I did a few sample emails to “[e-mail]”
I saved an Enigmail Debugging Log File.

Have I missed something in the Thunderbird or Enigmail configurations that is preventing Thunderbird from automatically attaching the Sender’s public GPG key?

As you wrote, you're reported this to Enigmail, which is an add-on.
