You can run it in the qmail startup script to support all
your existing .forward files automatically.
Individual users can switch to the .qmail mechanism at their leisure.
dot-forward supports forwarding, program deliveries, and comments.
It does not support file deliveries or :include:.
(However, it recognizes file delivery attempts,
and defers delivery to give you a chance to set up a .qmail file.)
