Hi Andre, Yes, we had a major problem with that on our Barracuda spambox yesterday. We have disabled the SORBS list until we figure out why/if it’s going to happen again. Every now and then we get one or two ranges on the SORBS list, but never half our clients at once. (on a large range of ISPs aswell).

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
