Yes. I assume your script somehow loops over directories and picks up one file at a time investigating it and then decides if it is spam. Then what you wrote above is the way to go. The possibility that the Message-ID of two different emails might be identical, is real, but that's luckily mostly the case for spam messages in my experience. But there is a safety hatch: While notmuch cannot search by file names, it is able to output file names, like so: notmuch search --output=files -- id:"100822114556.gc10...@example.com/" If you want to be extra cautious you could start with a file, get the Message-ID from it, decide upon the email in the file, then search for file names which notmuch associates to the Message-ID and in case of several file names, check them in turn... In case of the spam/ham decision, you then would have to decide what to do, if some files containing emails with the same Message-ID are spam and others are ham, since these are usually considered to be mutually exclusive. But I would be astonished if you would find such a case in a real file corpus of emails.
