user isn't a domain, just a hostname. Actually, I was hoping for
just,
user IN A x.x.x.x
user IN TXT "v=spf1 ip4:x.x.x.x -all"
but since x.x.x.x already has another hostname, a request for two
hostnames to a single IP has been refused in the recent past. So I
was just going to temporarily settle for the CNAME.
