How to turn off iOS spam filter

Thank you, Less.

I’ve tried the “move to inbox” approach in your 3rd link but it’s been unsuccessful. Another approach would probably be to add the sender’s address to my contacts. I resist this one since the majority of the false spam emails are from established newsletters (think Washington Post, NY Times) and that seems overkill for something that should never be flagged, in my estimation.

I appreciate what Apple is trying to do with its spam filter. I’m a long-time Apple user as well. I’m also reasonably capable with computer technology and have my own spam filters on my mail servers that work to my satisfaction. I’d be very happy to disable the Apple filter, especially as it falsely identifies spam, and deal with only one system. Can I do that?

My email provider has a default folder called “junk” and I control it’s sensitivity through the provider’s cpanel. When I access the imap server through Apple Mail a new folder appears called “spam”. Non-spam mail appears in that folder.

If I stop using Mail, delete the spam folder on the imap server and use a different email app such as Thunderbird or Outlook, the spam folder doesn’t reappear and the email that was previously placed there comes to my inbox.

Something happens when I use Apple Mail.

Thanks.
