So, I keep getting these error "we can't deliver" messages for email I didn't send in the first place. I assume some kind of spam generator has gotten into my shit somewhere?
So how do I figure which of my internet activities--web sites, blog, etc.--is being infiltrated and is generating this junk?
Here's an example, FYI:
Hi. This is the qmail-send program at server2e8.profesionalhosting.com…...
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.<majordomo@caballosalmeria.com>:
This address no longer accepts mail.--- Below this line is a copy of the message.

It IS a form of spam, what happens is the spammers send to a non-accepting but legitimate address knowing it will get bounced. Your email system then blindly accepts the fake can't deliver notification and bingo! you have been spammed.
Decent email systems can keep track of what they have sent out and reject bounce messages which do not correspond to those actually sent.
