Because you can only use $value inside a lookup expression.
Why is it like this?
(1) Because ${lookup...} was implemented a very long time ago, long
before "foranyaddress" was thought of.
(2) Because ${lookup...} can be nested, and $value is preserved at each
level, so the unset value gets preserved at the outer level.
It would make more sense to leave the value of $thisaddress set when the
testing loop exits. At the moment it is explicitly unset. I think this
would occur if the line
filter_thisaddress = NULL;
which is around line 1532 in filter.c in Exim 2.05 were just removed.
I will think about this possibility.
