Re: [exim] How can i expand a mysql query ?

Quoting Stanislaw Halik:

${lookup mysql {...} {${value}/.spambox}}

But where should it be delivered, when the lookup fails? When the
transport's directory option expands to an emptry string, the delivery
will fail temporarily (I think), and the message ends up in your queue.
