Updated by okurz about 1 year ago
## Observation
After the o3 migration, postfix is no longer able to reach the configured mail relay.
```
jbaier@new-ariel:~> sudo postconf relayhost
relayhost = [relay.infra.opensuse.org]
jbaier@new-ariel:~> host relay.infra.opensuse.org
relay.infra.opensuse.org has address 192.168.47.4
jbaier@new-ariel:~> ip r
default via 10.150.2.254 dev eth0
10.150.1.0/24 dev eth1 proto kernel scope link src 10.150.1.11
10.150.2.0/24 dev eth0 proto kernel scope link src 10.150.2.10
10.151.15.2 via 10.150.1.254 dev eth1

I believe the tun5 is/was the ssh tunnel to old-ariel.
## Acceptance criteria
* **AC1**: We are able to receive emails from o3 (again)
## Suggestions
* DCT migration related so open a thread in Slack #dct-migration (set reminder to yourself so that you ask again if there is no follow-up). If that does not work then we need to open an SD ticket and point to the Slack thread (duh)
* Find out the address of usable mail relay in PRG2 either in opensuse.org or suse.org domain
* Reconfigure postfix on o3 to use it
* Verify the operation
