Hundreds Of "delivery Status Notification (failure)" A Day

[WxGuy1]

I'm receiving hundreds of "Delivery Status Notification (Failure)"-type message a day ("undeliverable mail", etc). Last night, I received about 15-20 in the course of two minutes. In the headers, most say that the original mail was sent from "0stocknews@tornadocentral.com", which doesn't exist. I changed the default adddress for this domain to :fail:, though I wonder if that will only result in messages bouncing back and forth indefinately. Actually, I just looked, and I changed the default address to :blackhole:... Any ideas? Is this just something I have to deal with, or what's the deal? I don't want people sending out spam using an email address from my domain, if that's what's happening (I'm the only user of my domain).

I would change the default to :fail:

 

Anyone can spoof an email coming from your domain. It's called domain spoofing and happens to almost all of us.

Which is why the From: header is the most useless portion of an email when it comes to email tracing. Ignore it, ignore it, ignore it! Capable modern spam scanners ignore it.

 

The envelope headers can also be spoofed, but are more difficult to do so.
