Here’s a diagnostic report taken just after a very slight instance of the behavior in question: I selected a message and said “Train as Spam”, and SpamSieve did so, but it took long enough that I saw the faded yellow icon in the menu bar briefly. The Log shows the sequence starting about 8/31/26 at 6:53 AM, i.e. all the last stuff in the log. I wonder whether the Error -1758 is relevant here.
You will also see, around 6:50, SpamSieve initially evaluating the message in question and getting the answer wrong; this is a very good example of the sort of thing I’m suggesting SS needs to do better, i.e. the return address may look reasonable, but the button the user is invited to click in the message goes to some evil place (not to mention the improbable wording of the message itself).
Anyway, none of this is very much to go on, I’m afraid.
Thanks. It looks to me like the delay was in Mail loading the message source so that SpamSieve could look at it, rather than in moving the message. But this may be a different issue than what you reported earlier because before it never moved at all? Or are you saying that this one didn’t either?
I’m seeing error -1728. If the message did in fact move, I think this is probably a spurious error that’s simply saying the message no longer exists at the old location.
What do you find if you do a Words search of the Good Messages section of the Corpus for these words:
This one did move (“SpamSieve did so”). I only bring this one up because at least I saw something odd happen, namely the brief “yellow” icon.
With regard to your Words search in the corpus: They all do occur a few times (e.g. five or six times), in messages that were genuinely good (that is, they are in the Good Messages section, and rightly so).
As I said, it may be that this is not a good enough instance to give us any useful information about the “nothing happened” cases I reported earlier.
