# Enable Catch-All in Mailcow Setup a domain first in **E-Mail** > **Configuration** > **Domain** > **Domain**. Then, once the domain is setup, create an alias that you'll use, go to **Alias** > **Alias**. Create an alias like `casper@example.org`, then we can setup the catch-all next. To create an catch-all event, simply just use your domain for an alias. So create an alias called `@example.org` and set the Goto address to something like `casper@example.org`.
