Hello, I do have a weird issue. First the story.
I switch a new debian install (jessie) from the /etc/network/interfaces setup over to systemd-networkd. In addition I also enabled systemd-resolvd. The address assignment happens via DHCP and the nameserver is correctly entered into /run/systemd/resolve/resolv.conf which is linked to /etc/resolv.conf. Great! This setup works as expected. I do have connectivity and I can resolve names. One thing changed, the host picked up a link local ipv6 ( FE80::/10). Now almost everything works, postfix has an issue though. postfix delivers everything via a smarthost and here it fails. The mails are stuck in the mailq and the error message is that it could not get a AAAA record for the smarthost. That is actually correct because the smarthost has no AAAA record in the zone it has however a A record. This I do not understand. Why is postfix stuck with a ipv6 nxdomain while it could resolv the normal ipv4 address. I checked with nslookup on that host. It resolves just fine. =================================== nslookup -querytype=AAAA mail.itcfollmann.com Server: 10.0.11.212 Address: 10.0.11.212#53 *** Can't find mail.itcfollmann.com: No answer =================================== nslookup mail.itcfollmann.com Server: 10.0.11.212 Address: 10.0.11.212#53 Name: mail.itcfollmann.com Address: 52.7.212.38 ================================== Why does postfix even try to get the AAAA record. Documentation states actually that if not provided t defaults to: inet_protocols = ipv4 -H -- Henning Follmann | hfollm...@itcfollmann.com
