Send encrypted email in thunderbird

I am trying to send an encrypted email in thunderbird.
Code: [Select]
gpg --search-keys [email protected]
gpg: data source: https://185.125.188.26:443

Code: [Select]
gpg --export -a "<[email protected]>" > nous.key
I opened that in thunderbird but still error "No key available".

Just import another key:

It is NOT certain that the key belongs to the person named
in the user ID.  If you *really* know what you are doing,
you may answer the next question with yes.

Use this key anyway? (y/N) y

no idea how this works

Choosing 606520ACB886B428 does the same

why your master not Ed25519?

After adding also the key 3 I imported the file generated with this in thunderbird and now it shows encryption possible.
Code: [Select]
gpg --export -a "<[email protected]>" > nous.key

Edit: When I try to send the email some error happens.

"Sending of the message failed".

I had to select

Yes, I've verified in person this key has the correct fingerprint.
In Key Manager.

Not sure if I was suppose to verify something.
