Package: postfix
Version: 3.5.4-1
Severity: important

postfix cannot send mail if IPv6 is local only. In /var/log/mail.log
I've got errors like

Jul 10 09:53:22 zira postfix/smtp[865322]: 4C24DC218EE: to=<xxx>, relay=none, 
delay=2409, delays=2389/0.03/20/0, dsn=4.4.3, status=deferred (Host or domain 
name not found. Name service error for name=joooj.vinc17.net type=AAAA: Host 
not found, try again)

for several dozens of minutes.

FYI:

zira:~> host joooj.vinc17.net
joooj.vinc17.net has address 155.133.131.76

zira:~> cat /etc/resolv.conf
nameserver 127.0.0.1

But perhaps the error is due to that IPv6 is (currently) local only:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP 
group default qlen 1000
    link/ether 30:8d:99:25:ad:3f brd ff:ff:ff:ff:ff:ff

    inet6 fe80::328d:99ff:fe25:ad3f/64 scope link 
       valid_lft forever preferred_lft forever

I could eventually solve the issue with "service postfix restart",
then "postqueue -f".
