Exactly, usually people don't have control over their reverse. The
netblock owner controls reverse. If you have just a few IPs you
probably have no control over it, however at your server reverse DNS
should be configured as such.
Check running: host 208.101.58.177   (whatever is your server ip)
Then: host softlayer.com   (or whatever is its name)

Forward and reverse way must match, just as from 'outside'.
