Hello, I have reverse DNS [Not Set] (IPv6) and my ISP says they do not support IPv6 PTR record. This results in mails bouncing from some services, e.g. freenet.de:
host emig.freenet.de[2001:748:100:40::8:118] said: 550-inconsistent or no DNS PTR record for 2a03:xx::1 (see RFC 1912 550 2.1) (in reply to RCPT TO command)
What to do? I think I could disable the AAAA record in the box, or persuade postfix not to use IPv6, but how?
Does MIAB need a switch to disable IPv6?
Have a nice day, Jarek
