[nznog] SORBS had loopback listed in dnsbl?

Hey all, Anyone have an issue yesterday with mail being categorized as spam due to SORBS listing 127.0.0.1 in their DNS BL DB? Had a few complaints from internal customers that mail was not getting through, and a cursory inspection of the logs shows SORBS reporting this address as an open relay (I'm not sure if this a common occurence??). Would like to hear if anyone else had a similar experience. Cheers, Andre VFNZ
