Disallow foodsharing-related email-addresses as pw restore email-addresses
Description
Currently users can get locked out from foodsharing.de if they change their email address to their foodsharing.network address.
It's probably the same with lebensmittelretten.de-addresses.
(How many lebensmittelretten.de-Addresses are there and how should we handle them? Is there a lebensmittelretten-Mailserver? If anyone has ideas, please comments. Will probably edit this description thereafter.)
Goal
Disallow foodsharing related email addresses as backup for the profile-email-address.
Evidence
Discussion on https://yunity.slack.com/archives/C1T1ZM9A4/p1572520817415000.
Solution
Disallow (and probably also @lebensmittelretten.de-Adresses) as backup for the profile-email-address with a warning for the user ('Please use another email address so you can always reclaim your password for foodsharing.'):
