I'm doing something similar, but I'm searching "Maildir/cur" not

From my understanding, the mail "server" (MTA, LDA, ...) is supposed to
deliver new mail to "Maildir/new", and once a mail client has seen the
mail, it'll get moved to "Maildir/cur".

As such, deleting files from "Maildir/new" will only delete new, unread
messages, which sounds dangerous!

Of course, perhaps not all software that manipulates Maildir follows the
move-from-new-to-cur rule...
