all junk mail is going into my mailbox

If they are mostly from (say) Hotmail then sign into your hotmail account in Safari and check Rules and Junk mail settings there.

Ditto Gmail

If Mac Mail makes them junk they are usually brown.

Ensure Mail preferences for the account are set to trust mail headers

I have had the same problem for the past 3 days, I have been using Apple email App for over 10 years and never had my junk mail in my inbox.

I checked my Hotmail setting and there was no junk mail in my inbox but when I look on my iMac or iPhone my inbox is filled with junk mail, I called Apple and they just checked my settings and told me to click junk mail when removing then and I was already doing that. it’s something to do with them because I’m noticing a few threads on this topic. It’s annoying because I get a ton of junk mail and right now it’s only doing it to 1 of my 3 emails.

If thr problem is nit going to junk foldet then making sure that junk headers ARE trusted and exception rules kept to a minimum should be the route.

Personally I have the opposite. I get very little junk mail and I try to keep it in Inbox to avoid losing important stuff.

Maybe time to create a new email account. Bite the bullet.

Thank!

Today all seems to be working fine so what ever was going on has stopped and everything back to going to junk mail. I should just use a new email but companies will just sell it and I will be on another BS list or a company will have their system compromised and not saying anything for a year while your email is just floating in the dark web so you can get a million fake FBI or IRS emails or Russian babes waiting for me lol

just disgusting lol

Yes, I used to have two main email addresses, one "best" one that I kept for banks, insurance, credit cards, Amazon, Ebay and the government and another expendable one that I used for forums, minor companies and dodgy sites.

My expendable email NEVER got any junk mail, which suggested that the leaks were coming from one or two of the best institutions in the world.

I did once have an email address from our British Telecom that allowed you to set up dozens of aliases and you could use the company name in the alias so that any junk mail could be identified as coming via that company'sleaks. Regrettably they just denied responsibility.

What did you mean by

"My hotmail and my mail on the mac are linked together "
