Blocking an address on mail app with notification?

Hey there, unfortunately I'm finding myself in the rather unpleasant position of having to block somebody from contacting me altogether, and that includes my email addresses.

It's a very long, complicated story so I'm gonna spare y'all the details, but basically I don't just need to avoid receiving/reading their emails, like you would for purely sanity-preserving reasons; I also need (if possible) to have them get some kind of system message that the address has been blocked, so it's clear I'm not reading. That's why it's not enough just to delete whatever comes as soon as I get it, or set up a rule thingy that immediately deletes the email as soon as it arrives. So unless having the automatic deletion rule in place generates some kind of error message to the effect that 'this user is no longer accepting mail from you/email address no longer valid' that is bounced back to the sender, I will need some other solution.

I did try to look it up, but all I seem to be getting is the rules option, but as I seem to have heard of other things in the past I thought I'd ask you guys just to make sure Plus with anything that has more than a couple parameters it's always a good idea to also discuss it with a couple knowledgeable people as humans have the added bonus of synthetic thought

Thanks in advance!

 

hey Mal, thanks for the reply, unfortunately it's not gmail but just plain ole yahoo
