First thing I did was create a mailbox called catchall@domain.com' in the Mailboxes Manager inside the Panel then went to roundcube and made sure I could login to that account (Just like to be sure it was working first).
Then back into the Panel and went to Mail > Aliases and created a new alias like below:
Alias Address: *@domain.com
Destination: catchall@domain.com
Wait a day or so and login into the catchall@domain.com using roundcube and check out the spam! LOL
