In this week’s blog post we will look at all the settings of Enigmail on Ubuntu. If your Thunderbird looks different than ours or you’re missing some options, you’ll find your answers here. And, as always, you can also watch our instructional video that’s at the bottom of the post.
As you’re watching/reading our how-to-guides, you may get stuck because you just simply cannot find the correct option, settings, button, tab… Unfortunately, Enigmail will set up itself automatically without asking you first – sometimes you’re lucky and it’s set up correctly, sometimes it’s like you’re using a totally different software.
The chapters bellow will help you with the most common differences that occur:

You’re accessing the Enigmail sub-menu in nearly all of our how to guides. Your menu might look different than ours though, it may show Enigmail/p≡p sub-menu instead of simply Enigmail. Enigmail/p≡p does not offer the options we need so here’s how to change it:
New window will open
And that’s it, you can close the window.

You may also run into the problem of the Sign and Encryption buttons being disabled when you try to send an email. Here’s how to unlock them:
Here you need to have these settings checked or selected:
Save the settings by pressing the OK button.

Enigmail may automatically encrypt/un-encrypt or sing/un-sign messages that you are about to send. This may get frustrating if it keeps checking and unchecking the options that you want or don’t want to use. This is accessed the same way as the previous step:
In this window you can decide whether you want to encrypt or sign every message by default as well as id you want to encrypt draft messages or sign encrypted or non-encrypted messages automatically.
Even if set here everything accordingly to your needs, Enigmail may still misbehave. Here’s what to do next:
Here you can additionally change the Enigmial preferences for sending. Save the settings by clicking the OK button when you’re done.

For security reasons, it is very beneficial to always check whether you’re sending encrypted emails with the key of the correct person. Unfortunately, Enigmail – because of its default settings – won’t prompt you to check the key before sending an email. Here’s how to get it work:
As you may notice, new tabs appeared at the top of the window
The option “Always (also) Manually” is the most important, it will give you the chance to always double-check whether you’re using the correct key when encrypting emails.

Thanks to clicking the “Display Expert Settings and Menus” in the previous step, new options appeared in the Enigmail sub-menu.
Most notably the option “Manage SmartCard…”. This option allows you to quickly get to the window where you’re changing PIN codes, generating new cryptographic keys or personalizing your Cryptoucan™.
