Resolve an spf version 1 record of a hostname
fdnsspf1 <hostname>
fdnsspf1 will attempt to look up an SPF version 1 record for hostname. If one is found, it is printed to standard output and the program exits with return code 0. If more than one is found (a violation of the specification), none is found, or the DNS query fails, nothing is printed and the program exits with return code 1.
