dot-forward reads sendmail's .forward files under qmail. 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.)
