I e-mailed their ISP, the response was "You aren't receiving mail from
mediaone.net because it is a defunct domain, and if you are having mail loops
caused by that IP address, your mailer software was poorly written and should
be able to recognize that as a bad IP address and halt the delivery attempt."
I kinda agree on that one. Exim should be able to tell that 0.0.0.0 is an
undeliverable IP address. I get a lot of mail frozen in the queue for mail
servers with an IP lookup of 127.0.0.1 also. I really wish Exim would
immediately kill these messages.
