[exim] Wildcard aliases do not work

Greetings,

I have installed 'out-of-the-box' exim 4 on a Fedora 7 system and
tried to make this trick: to have all the addresses starting from,
say, 'mailer-' be forwarded to the same local address.

The string

maler-*: localbox

in /etc/aliases doesn't work. The catch-all alias

*: localbox

doesn't work, either.

May I ask for an advice how to handle that? The documentation isn't
clear enough on that.

Thank you.
