Well, you would simply call mailbox_open(ns->list, "INBOX"). Dovecot
internally then figures out that INBOX is /var/mail/%u based on the
namespace's configuration.

I'm not sure what you mean. I was thinking it would do exactly what it
does now. You give it source and dest mailboxes and it moves messages
from one to the other. (Although one minor optimization could be done:
If no messages are moved, don't call the final mailbox_sync()).

Also note that nothing here now assumes anything about what mailbox
format is being used. The whole plugin should perhaps be renamed to
"snarf", since it would work with any mailbox formats
(source/destination could even be different formats).

You probably want to hook into mailbox_allocated and do the method
overrides there. For that there are many examples in most existing
plugins, like lazy_expunge.

You can implement that by overriding mailbox.notify_changes method and
calling mailbox_notify_changes(snarf_mailbox) and implementing a
callback handler that does the snarfing whenever it's called. (And also
implement the notify_changes removal code.)
