Isn't .forward typically in home dir, not under maildir? I don't know about per-user aliases file (there's such a thing?), but I'd guess that is also under home dir.

It can't do delivery as net-mail group if they're 0700.

None of those can work either with net-mail group permissions since all the necessary dirs are 0700.
