Registering *with* email?

[panzi]

Is there a way to pass the email (and other meta data) certbot shall be use for the certificate?

Looks like the current docker file explicitly does the registration without email. There may be a reason for that.
Running certbot register --update-registration --email new_email@address.org or certbot update_account --email new_email@address.org should do the trick.
