This is the key... you are apparently getting a soft reject because your
IP address, or the IP address of your ISP, which is 194.65.79.222 does not
resolve to anything... there is no reverse delegation, or any delegation.
Many mail servers will reject incoming IP addresses that do not resolve to
anything as a line of defense against spam.  I do.
