[EXIM] 1.80 mail lists broken?

I can't seem to get mail lists to work with 1.80. Here's my setup:
I have made a list in file /usr/local/lib/exim/lists/sng. I can
verify fine. But when I send a real message it fails, saying:

1997-12-15 13:52:12 0xhfcA-00071n-00 == sng@??? D=userforward defer (
-1): userforward director failed to stat /local/users/sng

But verify is fine:
exim -bv -v sng
