You don't strictly need the condition. Plus, you don't need the second
argument to substr when you want the rest of the string. And I think you can
use the in operator in the query.
maillist:
driver = redirect
data = ${lookup{${substr{0}{5}{$local_part}}}lsearch{/etc/exim/maillists}
{${lookup mysql{select email from $value \
where ${substr{5}{$local_part}} \
in (class1, class2, class3)}}}
The first lookup searches /etc/exim/maillist. If the key given by the first
five characters $local_part is found, the value is put in $value and the
true-branch of the lookup item is expanded. In this case it's a second
lookup. If either lookup fails to find any data, the router declines. This
isn't exactly the same as the condition not matching, but it only matters if
no_more is set (and possibly some more situation that I might have
forgotten.)
