Mail: spam with no reply address. How to stop?

[Miqs]

I am getting spam emails that have no reply to address so I can't apply rules. Is there anything I can do to stop or just move to junk? It seems I am helpless to prevent these. I don't want to click unsubscribe for obvious reasons.

Read the Apple Support document iCloud: Why am I getting Junk Mail on iCloud.

Every email has a short summary of where it came from, what the subject is, etc.
But that is the consumer friendly version.

There is a big header behind the curtain that you can take a look at - sometimes called like 'show original' or 'display full email header', etc. Depending on what app you use and which operating system.

The full header usually discloses more details, even if there is a spoofed empty from: (not sure WHICH provider would even ever allow that and doesn't auto bounce it back, but okay.. ) then other patterns from these spam emails might be figured out. But my guess is that the full header will actually have some return address listed.

Thanks. For your information the constant "no reply" spam emails I am getting has been solved. I have created a new rule which stops all emails received with no @ in the title. This has worked as I received 4 today which have been placed immediately into my trash folder. I also learn that if anyone receives dubious emails without a "reply to" name then you can go to View > Message > Long Headers or View > Message > Raw Source which shows all sender data.
