My specific application: I am running spamassassin and would like users to be able to submit spam (and ham) directly by moving it into special folders.

I did this before switching to antispam. I use antispam with spool2dir now, that central directory has a inotify watcher that trains the messages instantly.

This is a great idea. In my case I think I will get away with a five minute cron job since the pickup latency should be manageable to the users and there is less to install. But I like in principle the idea of an immediate, fs-driven trigger, which would probably use fewer CPU cycles in the aggregate.

[...]all my users moved messages into spam/yes, but copied them into spam/no

Unfortunately I can't rely on users getting this right, much less understanding the difference between copy and move semantics. And I'm probably not going to be able to upgrade my users.

Thanks for your advice!
