It does? Is this stored in an expansion variable or is it just automatic?
(i.e. exim detects that the current lookup is identical to the previous one
and uses that result)

Nice idea, however to quote the documentation
<!-- Begin Documentation Quote (
http://www.exim.org/exim-html-4.20/doc/html/
spec_14.html) -->
address_data
Type: string, expanded
Default: unset
The string is expanded just before the router is run, that is, after all the
pre~con~dition tests have succeeded.
<!-- End documentation quote -->
Since it is expanded after the preconditions (local_parts, domains, condition)
then surely if the router is skipped because of a condition failiure it is
not set so i cant use this in the other routers.
Is there another setting i can use which is expanded before the preconditions?
(cant see one in section 14 of the docs)
Thanks for your input
