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.)
