Is anyone else having this issue? And any suggestions as to how to sort it out? I'm getting emails bounced with the following error message: Although that IP is dedicated to one web site, the actual listing on SORBS is an IP block listing. It seems the TTL setting for the IP block is getting SORBS in a tiz. I've raised this as a support ticket with Knownhost and they suggest I request SORBS to have the IP excluded from the block listing. This has not gone well, although why is unclear as SORBS has not responded to my request made on 29 November. I'm no techie - I don't understand the issue. And I seem to be running out of options to get off this listing which, it seems, has nothing to do with my website. HELP! Please.
