Uh oh!

I have discovered that the SMTP configuration in Keycloak does not follow IPv6 Happy Eyeballs. When using an FQDN for an SMTP server that only accepts connections on IPv6, it fails to work. The SMTP server has both an A and AAAA DNS record. Setting the Host to the IPv6 address works.
I know I can make this work in other ways but I think it should follow the standard of using IPv6 first.
