Email Question

Is there anyway to make all email that comes to a domain bounce or be deleted, unless it is addressed to a mailbox that has been specifically defined.

IOW, I want * to be deleted and only those mailboxes I have set up get email.

Most of my spam comes from [random_letters]



Go to the Mail -> Addresses section in your control panel and look for the address defined as “*”. That’s the catch-all. You can either just delete it or edit it and set it to “Bounce” etc.
