What is the default address?
It is a catchall mailbox that receives all emails written to a non-existing name @ your domain.
Why is this disabled?
We disable Default Address because if you don't know how to use it, it can cause your account to flood with email.
How do I enable it?
This can only be enabled on Cloud Servers:
http://www.hdwebprovider.com/cloud-servers/
Once enabled, what do I do?
Set every catchall to :fail: no such address here. This will prevent your account from filling up with unnoticed spam.
