[Exim] appendfile transport change in 4.20

from the Changelog:
> 34. Changed (incompatibly, but hopefully not so it affects anyone) the
> appendfile transport in the case when it is called directly as a
> result of a .forward or a filter file requesting a delivery to a file.
> Previously, any settings of "file" or "directory" were ignored in this
> case. Now they are used. The path received from the router is in
> $address_file (as before) and can therefore be included in the
> expansion.

I suppose this is why my filter isn't working anymore... I'm too tired
and busy sorting my inbox right now to see what i need to do to make it
work again. Please help me...

Below is a address-test in filter-debug mode and my
maildir-transport-config.

Wbr,
Richard
