You can set an alias where the left hand side of the 'Email to' is empty. This will show in the alias list as something like:
-any-@example.co.uk catchall@example.co.uk
But the instructions on the web page are a little misleading - this is indeed a catch all to 'match any addresses for which there is not another alias (even if there is a mailbox that matches)' - but the alias file is processed repeatedly until there are no more aliases, and you can find most mail gets
mailbox_name@example.co.uk -unchanged-@example.co.uk
and this will terminate the alias processing and delivery to that mailbox will happen.
If you're not careful on the web interface, you can end up pressing 'OK' where all the fields are empty. This gives an entry in the alias list something like:
-any-@example.co.uk -unchanged-@example.co.uk
which just confuses the situation. Especially if you have this entry as well as a catch all entry with a 'Send to' address: -then addresses with their own aliases will be delivered twice (once to the catch all, once as specified in their own alias); addresses without their own aliases will be delivered once (to the catch all) and the sender will receive a 'mail rejected' reply (as there's no specific alias).
