It supports POP, IMAP, SMTP, S/MIME, and OpenPGP encryption (through the Enigmail extension).

Sharing the public key
There are a variety of ways to distribute the public key. One way is to upload it to a public keyserver network. Another is to share it with friends who are also using email encryption.
First of all, encryption does not always work properly with emails containing HTML. It is best to make all of the encrypted emails plain text by choosing Options > Delivery Format > Plain Text Only in the new email window.
Once the email is finished it can be signed through the OpenPGP menu.
Assuming that the email was encrypted properly, just trying to open it should result in a popup window asking to type in the keyphrase.

Tips and tricks
Setting the default browser
Recent versions of Thunderbird use the default browser as defined by the system MIME settings. This is commonly modified by the Gnome Control Center (Gnome Control Center > Details > Default Applications > Web) (available in: ).
This can be overridden in Thunderbird through Edit > Preferences > Advanced > General > Config Editor by searching for
If the following three are all set to
false (default), turn them to
true, and then Thunderbird will ask you when clicking on links which application to use. Depending on the chosen desktop, common values include
/usr/bin/exo-open (Xfce) or
/usr/bin/xdg-open (non-DE environments). Remember to check "Remember my choice for .. links".

Plain Text mode and font uniformity
Plain Text mode lets you view all your emails without HTML rendering and is available in View > Message Body As. This defaults to the Monospace font but the size is still inherited from original system fontconfig settings. The following example will overwrite this with Ubuntu Mono of 10 pixels (available in: ).
Remember to run
fc-cache -fv to update system font cache. See Font Configuration for more information.
<?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <match target="pattern"> <test qual="any" name="family"><string>monospace</string></test> <edit name="family" mode="assign" binding="same"><string>Ubuntu Mono</string></edit> <!-- For Thunderbird, lowering default font size to 10 for uniformity --> <edit name="pixelsize" mode="assign"><int>10</int></edit> </match> </fontconfig>
