I suspect that this is more of a test for whether the domain is real and looks superficially in use. I looked a few hits on this and only one even had a whois entry. If anyone want to try it, I suggest doing it as: __NO_MX_FOR_FROM && ! NO_DNS_FOR_FROM -- You are receiving this mail because: You are the assignee for the bug.
