LinuxQuestions.org - Enigmail on Thunderbird with GnuPG keys

You do not have to use Enigmail to do that. In fact I am not sure how to do that with Enigmail.

Use gpg commands (command line)

Code:

gpg --keyserver pgp.mit.edu --send-keys YOURID

man gpg for more details:

Code:

--send-keys [names]

                Same  as  --export but sends the keys to a keyserver.  Option

                --keyserver must be used to give the name of this  keyserver.

                Don't send your complete keyring to a keyserver - select only

                those keys which are new or changed by you.

And also read the first chapter of the manual available on gnupg website.

Alternative to command line sending. You can summit your public key via web interface. Just do a search on pgp keyserver. And click any of them. The gnupg handbook on this: http://www.gnupg.org/gph/en/manual.html#AEN65

on your machine

Code:

gpg --armor --export USERID >> USERID_publickey.txt

and submit the content of the file to the pgp keyserver.
