Hi to all,
I have disabled

ipv6 on my systems. I am getting exim paniclog, daily.
Nothing worrying, but annoying. The same problem is on Debian 9/10, Ubuntu 16.04/18.10 systems.
Any ideas?

### Log
exim paniclog /var/log/exim4/paniclog on hostname.localhost has non-zero size, mail system might be broken. The last 10 lines are quoted below.

2019-09-13 14:20:56 IPv6 socket creation failed: Address family not supported by protocol
2019-09-30 13:06:06 IPv6 socket creation failed: Address family not supported by protocol

As per https://bugs.exim.org/show_bug.cgi?id=1374

I have edited, but the problem persist.

1) $/etc/exim4/update-exim4.conf.conf

$ disable_ipv6='true'
$ dc_local_interfaces='127.0.0.1'


2) $/etc/hosts

$127.0.0.1 hostname.localhost hostname

# The following lines are desirable for IPv6 capable hosts
#::1 localhost ip6-localhost ip6-loopback
#xx03::1 ip6-allnodes
#xx03::2 ip6-allrouters


3) $/etc/exim4/exim4.conf.template

$#disable ipv6
$disable_ipv6 = true


$update-exim4.conf
$systemctl restart exim4.service
