FastMail’s spam filter has been a bit aggressive lately. I’ve seen a few emails show up in the Spam folder these last few weeks that were legitimate. I guess I’ll have to check it more often than I have been.

@mcg Ah cool. Thanks for that. I'll leave the levels where they are for now, but I'll look out for the borderline false positives, and if they're close to the threshold, I'll consider lowering it a bit. I should probably be better at training the Spam filters as well, either reporting it or marking it as not spam.
