Package: postfix
Version: 3.1.0-5+b1
Severity: normal
Dear Maintainer,
in my /var/spool/postfix/etc/resolv.conf file "nameserver" line is missing, so
Postfix cannot send emails and reports "delivery temporarily suspended: Host or
domain name not found. Name service error ..." errors in mail queue.
/etc/resolv.conf content is:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 10.0.11.1
while /var/spool/postfix/etc/resolv.conf content is:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
Relevant /etc/network/interfaces content is:
auto br_adm
iface br_adm inet static
address 10.0.11.19
netmask 255.255.248.0
gateway 10.0.11.1
dns-nameservers 10.0.11.1
bridge_ports enp1s0f0
bridge_fd 0
If I restart Postfix using the command "systemctl restart postfix",
/var/spool/postfix/etc/resolv.conf file get in sync with /etc/resolv.conf and
Postfix starts working normally.
But after a system reboot "nameserver" line always disappears from
/var/spool/postfix/etc/resolv.conf file.
If I modify the script /usr/lib/postfix/configure-instance.sh adding a delay
everything works fine, /var/spool/postfix/etc/resolv.conf stays in sync with
/etc/resolv.conf even after a reboot.
To add a delay I added the command "sleep 5" before the line
"FILES="etc/localtime etc/services etc/resolv.conf etc/hosts \".
I know I could remove resolvconf package and use a static /etc/resolv.conf but
I think this bug could affect other users that need resolvconf.
