It's working as expected. To get a green bar in Enigmails header
display, the key signing the message has to be at least fully valid. A
key gets valid if you either:

- sign it (whether local or exportable is not relevant)

or

- it is signed by
  - at least one key you have signed and you have put "full" ownertrust
    on these
  - at least three other keys you have signed and you have put
    "marginal" ownertrust on these

This is the behaviour of the "classic" or "PGP" trust model which is
the default in GnuPG. Enigmail only displays the result.

You may read more about this here:
https://enigmail.wiki/Key_Management#The_Web_of_Trust

There's a lot more information about the web of trust out in the web.

Disclaimer: Configuring GnuPG to use the TOFU trust model may change
this behaviour.
