[Exim] ldap and .forward files

Hi,

I use exim with a lookup facility to identify the local user. First I
check the alias entries, then the uid entries and finally deliver
anything remaining to my dummy-user.

I have the standard "userforward" director and that appears to only
enable the processing of "forward files" for mail destinations where
"local_part=existing local user".

How would I go about enabling the forwarding for my alias users?

Thank you very much,

Oliver Seidel
