To set a catch-all mailbox for your account:

  1. Go to the Mail Manager section.
  2. Go to the Catch-all tab.
  3. Select the Domain and Catch-all mailbox.
    Catch-all

The catch-all mailbox will only collect messages sent to non-existent addresses under your domain.

Email forwarding, SpamAssassin, and antivirus protection cannot be enabled for the catch-all mailbox. This is a performance-related restriction.
