i’m receiving lots of spam emails on the daily but the recipient’s email isn’t even mine? (and it doesn’t actually exist either)

Someone with your email address leaked it somehow and you are on a list for sale to spammers on the web.

If you never normally get mail via a bcc then you can set up rules in most decent email provider's web account to junk any mail without your address in the to: field. Look for mail rules.

You just have to scan the junk folder for good mail. Some allow you to whitelist the mail from your contacts only or from a list.

What is happening is that the spammer has put one address, possibly fake, in the 'To' field, and a list of recipients in the 'BCC' ('Blind Carbon Copy') field. This is hidden from all recipients, and is used, often in legitimate mailing lists, to prevent recipients being able to see tha addresses of other recipients.

IOS version has no impact on spam unless a third party app is being used to block it and the app developer is behind with testing and updates.

The sender is able to spoof the sender snd the receiver address,

Tap on the to: address and expand it. It must be yours unless your email provider has lost touch with reality.

"...They have done something to the iOS 15 that has opened the door to this problem...,"

Very unlikely. Junk is managed primarily by your email provider . Google how to filter junk in your email web account

The iOS update is of no relevance.

All you can do is move them to the junk folder and hope the mail system learns.

One of your contacts maybe had their non-2FA email account hacked and they got your address to bombard you with spam.

What I started doing is tapping the email address to block the spam, then I click “move to junk”. That seems to have helped a lot. I still think it has something to do with the latest iOS upgrade.

I agree with you about the emails. I am getting slammed with all of these emails that I would expect to see in my junk folder. I’m sure it started with the iOS 15. I am constantly having them blocked and sent to junk. They have done something to the iOS 15 that has opened the door to this problem. . I never used to get this stuff directly into my email box. It’s very frustrating.

Who is your email provider.

Google?

Response edited as I didn't notice you were not the original poster.

So why is it also happening to someone with an iPhone 6?

Is the iPhone 6 supposed to have some special spam blocker?
