Information link for setting up external e-mail aliases is dead
I want to use mailbox.org to handle the e-mail of a domain I own. I therefore went to add an external e-mail alias. That page says "By setting this security key, you are confirming that you have read the Help section, that you know what you are doing, and that you are aware of the consequences". Naturally, I want to read the linked help section, but that link is dead. This is not instilling a lot of confidence in your service. Please advise.
