As others have said, it's a DNS issue. Specifically, your config has (IMO correctly) checks enabled on the HELO hostname. The list server is sending HELO=tupac2.dyne.org, and your server is trying to resolve that - the specific message means that DNS lookup is failing. It's resolving for me here (otherwise I wouldn't be getting list messages !) so you need to look at your local DNS setup. What do you get if you ask "dig tupac2.dyne.org" or "host tupac2.dyne.org" ? _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
