[keycloak-user] Cannot send verification/update password email behind reverse proxy

[Dave B]

Hi all,
I'm really struggling with this one. We can't send verification emails when
the docket image is behind a reverse proxy. I'm using nginx and everything
works apart from the email functionality, none of which works. We can get
tokens, verify tokens etc. But no email functionality works.

The realm functions fine on a local instance and sends emails as expected.
Can't see anything in the logs. This is a killer for us so if anyone has
any ideas please contact asap.
