I've done absolutely everything that has already been suggested, before it was suggested. My last resort was to uncheck the "Trust Junk Mail Headers" box as suggested above. This may end up being an issue because my decades-old Hotmail email is connected to my iMail app, and we all know how Hotmail is for spam.
In any case, it makes absolutely no sense that a sender made "VIP" should have emails automatically routed to Junk, even after multiple replies have been sent to them, on their multiple sent emails.
I've been losing money for months because of this glitch, you know, so I hope you don't expect my tone to be sunshiny and flowery, teeheehee. If I had any say, I'd be using an email my cellphone provider supplied because they were 100% reliable, gave push notifications almost immediately, and had no overzealous junk mail routing algorithms to intercept legitimate money-generating, time-sensitive emails. Alas, this is a service they no longer provide.
Meantime, hopefully the "Trust Junk Mail Headers" suggestion will work (and I won't be bombarded by decades-old Hotmail spam) because precisely none of the other tips have.
Thanks anyway,
