Im getting quite a few of these in my postfix log: Aug 24 03:19:07 hasna postfix/smtpd[43077]: warning: xx.xx.xx.xx.relays.osirusoft.com: RBL lookup error: Name service error for name=253.252.37.68.relays.osirusoft.com type=A: Host not found, try again
Is it an error from osirusoft or something from my machine?
