===== How do I set up a catch-all email address to receive or bounce invalid inbound emails? =====

  - Virtualmin
  - Choose the domain name of your server from the pull-down menu
  - Click "Edit Mail Aliases"
  - Click "Add an alias to this domain"
  - Set "Name" to "All mailboxes"
  - Fill in the delivery settings as usual (a local mailbox, usually).
  - Click "Bounce mail?" if you want to use this catch-all email account to bounce inbound emails with invalid email addresses.


To "turn off" the automatic email bouncing, simply delete this catch-all email alias.
