1. Please check your routers. I get
$ exim -bt info@???
info@??? is undeliverable:
all relevant MX records point to non-existent hosts or (invalidly) to
IP addresses
2. Please check your nameserver. I am using bind. If you are using
another dns server I think there is at least one that does this
automagically behind your back.
