Kiyokazu in (hopefully) hacker mode (A patch to Exim 4.50)

Lookup by embedded Perl of Exim 4.50.

exim-4.50-askperl.diff.gz

is a gzip'ed unified diff from Exim 4.50 to add a new single-key lookup askperl;<name> which calls perl subroutines. For each lookup, you should define 3 subroutines with names of the forms <name>_open, <name>_find, and <name>_close.

<name>_open: is passed no argument. If the return value is `undef', it implies failure of opening the database. Othewise the value is passed to <name>_find as the 2nd argument.
<name>_find: is passed 2 arguments. The 1st argument is the lookup key, and the 2nd is the return value of <name>_open. If the return value of <name>_find is `undef', it implies failure of the lookup. If the return value is an empty string, the lookup is treated as defered.
<name>_close: is passed the return value of <name>_open.
