This is a temporary error. The name server for monsant.com could not be
contacted. You don't know if the domain exists or not. "whois" shows this
domain does exist, but the listed name servers return an error rather than
an authoritative NXDOMAIN.
I am getting an NXDOMAIN:
# host monsant.com
Host monsant.com not found: 3(NXDOMAIN)
It's possible that their different name servers return
different reponses. At any rate, it was a temporary error
when postfix tried to deliver the mail. If postfix gets an
authoritative NXDOMAIN the mail will be returned, just like
with the asdf.gmail.com example.
