Movemail then move back was Re: [Evolution] Movemail, why?

[Hassan Aurag <h_aurag yahoo com>]

Ok, I understand there might be many problems.

Now evolution, netscape mail, and others use some
movemail to be able to avoid locking, setuid, setgid
... Great!

Then please move it back once done with it. In other
words fake imap even on systems without imap! This
shouldn't be a problem since those files are local
even though they might be coming from nfs.

Would that be too much work?
