The following error was found by staring at o3 logs out of boredom:

AC1: Mail sending works

Suggestions

  • Find a replacement for relay.infra.opensuse.org, ask openSUSE heroes and/or SUSE IT EngInfra, create tickets and wait for answers

I asked in #opensuse-admin IRC as well:

cboltz okurz[m]: I can at least recommend not to use relay.i.o.o from openqa ;-)
relay.i.o.o is (and also the nameservers knowing it) in the heroes network, which is probably not reachable from the openqa network
better use a server inside the openqa network
okurz[m] @cboltz it seems this got changed, could be two years ago, maybe by tampakrap at that time. Since then it seems we have no email forwarding out of that zone

Suggestion: Ask openSUSE heroes and/or SUSE IT EngInfra for the best solution how to send emails to a mailing list, preferrably o3-admins@suse.de but we can also create a new one, maybe openSUSE dedicated

With help from Daniel Rodríguez over SD-Ticket and Bernhard Wiedemann over chat we could fix the problem.

sudo echo 192.168.47.4 relay.infra.opensuse.org >> /etc/hosts && sudo sed -i -e 's/disable_dns_lookups = no/disable_dns_lookups = yes/' -e 's/inet_protocols = ipv4/inet_protocols = all/' /etc/postfix/main.cf && sudo systemctl restart postfix

also see https://serverfault.com/questions/626249/delivery-temporarily-suspended-host-or-domain-name-not-found

And I received emails immediately. So fixed.

I asked for a proper DNS fix in the SD ticket and Bernhard gave me a good fix how to resolve it. I implemented these changes on o3 by adding

server=/infra.opensuse.org/192.168.47.4

to /etc/dnsmasq.d/openqa.conf and set itself as resolver with

NETCONFIG_DNS_STATIC_SERVERS="127.0.0.1"

in /etc/sysconfig/network/config. If you see problems it is just a matter of restoring the old NETCONFIG_DNS_STATIC_SERVERS (there is a commented line right above the new one) and regenerate resolv.conf with netconfig update -f
