# This router handles forwarding using traditional .forward files.
# It also allows mail filtering when a forward file starts with the 
# string "# Exim filter": to disable filtering, uncomment the "filter" 
# option. The check_ancestor option means that if the forward file 
# generates an address that is an ancestor of the current one, the 
# current one gets passed on instead. This covers the case where A is 
# aliased to B and B has a .forward file pointing to A.

# For standard debian setup of one group per user, it is acceptable---normal
# even---for .forward to be group writable. If you have everyone in one
# group, you should comment out the "modemask" line. Without it, the exim
# default of 022 will apply, which is probably what you want.
