I guess that means you wouldn't need a username/password, for that..., just a small program
that opens/closes recenty changed folders, ok.

I wouldn't mind a little overhead.

I think this would work (I was just suggesting a daemon, because I know dovecot can also keep
things mmap'd).

I like that idea, but it wouldn't solve it, for the situation where you'd use procmail for
delivery.

(unless ofcourse the LDA does filtering/sorting as well, which sounds like a lot of work)

Where a small patch to procmail which uses standard out for telling the LDA or wrapper what
files it delivered to, would be pretty easy.
