I have been getting similar spam from a variety of email addresses. Looking at the default headers, I find that the only similarity is in the
Authentication-results header. For example, here are the headers from two different emails:
Is there any way I can set up Apple Mail to block, say emails with
Authentication-Results=atlas???.aol.mail.ne1.yahoo.com? Or is there another way I can block this?
I didn’t want to publish the entire header from each email, but I don’t know whether this is enough information, either. I’ll be glad to post any further header info on request. TIA
