I have a message for en.internet.nl <http://en.internet.nl/> advising me that “Modern internet address? Not reachable or improvements possible (IPv6)” -> "Unfortunately, this e-mail domain can not be reached by senders using modern IPv6 addresses or there is an error in its configuration. It is not yet part of the modern Internet. You should ask your e-mail provider to enable IPv6 or to fix the issues in its configuration.”
So I’m trying to figure out just what it is thats wrong with it. I’ve had something of a similar message from Gmail. My service provider only recently enabled IPv6 for customers, and although I’m pretty far along with it, I could use a checking server somewhere that actually delved into it a bit. Does Postfix need anything special - I can’t see anything in the docs. Thanks Robert
