Yes, I realize that. The way that we got here is that, with Sonoma, Apple forced a switch from a mechanism (plug-in) that was reliable and fast to one that was unreliable (extension). At that point, our first priority became finding a way to make the filtering reliable before Sonoma was released. Now we have Filter spam messages in other mailboxes, and it works, although it’s slower than I’d like with large mailboxes. I have some ideas for how to make it faster in the future, and of course it’s also possible that Apple will fix the bug with extensions so that none of this is needed in the first place. It’s also possible that we’ll figure out what triggers this bug, since it only affects a small percentage of users, and then only intermittently—so maybe there is some way to avoid it.
