digest and foreign_submit

I have been through the FAQs and Manual in an attempt to solve my digest problem. When I uncomment "foreign_submit" in rc.custom it breaks the ability for my subscribers on the digest version to originate submissions. The indication is that they are NOT on the accept list. Does this mean that I have to unlink dist and accept on the non-digest side. I want to restrict submissions to only subscribers. Thanks, Harlan Olson
