<You are NOT allowed to own a domain and not have a valid DNS server
for it. The server might be unavailable, it might be outdated but it
MUSt exists in the record for a domain being granted to you.>

I stand corrected. If your DNS happens to be down, your hijacked..


<Maybe that's one more reason why rejecting mail based on the sender's
domain existence is NOT a good idea (even if many people do it).>

Rejecting based on this info has always been a good practice in the
fight against spam.
