key, and hence your whole key pair is now useless.

There is no way to recover your private key, either. It cannot be obtained from

your public key or from any message that was signed/encrypted by that private

key. You can only recover it if you made a backup in the past.

Hence, losing the passphrase or the key is definitive. If you generated a

revocation certificate (and you should have), use it to revoke the key pair. You

must also generate a new key pair, send the new public key to your contacts

and warn them not to use the old public key any more.

Messages that were sent to you encrypted with the old key cannot be decrypted

any more. Messages that were signed by you with the old key can still be

verified by the recipients by using the old (revoked) key.

To avoid this disaster, it is recommended that you backup in advance your key

pair: from Key Management, select File → Export Keys to File, make sure you

included the secret key, then store the file in a safe place. Make sure you

chose a passphrase you can remember, too.

10.1.16. After I reinstalled Enigmail, all keys have

disappeared from the Key Management window.

The keys are still there, but are displayed only the keys that match the search

criteria entered in the Search for field. If you want to see all keys, tick the

checkbox Display all keys by default.

10.1.17. I get an error whenever I try to post to a

newsgroup.

You are trying to post an encrypted message to a newsgroup. This doesn't

make any sense as a newsgroup, like a mailing list, is a public space and not an

entity that could own a key pair. (Just ask yourself: who is supposed to own the

private key? What would be the trust associated with this entity?)

Send your message unencrypted. If you just want to obfuscate information, like

spoilers, you can as well use ROT13.

10.1.18. I have set forwarding rules on Thunderbird, and I

get an error “Sending failed, please check your

settings”.

Unfortunately forwarding rules do not work in Thunderbird with Enigmail

installed. Currently there is no solution or workaround for this issue.
