I rebuilt _after a (noop) `git pull`_, and now it seems to be working with the second domain added to Postfix’s `relay_domains`. Before these series of tests, and with the change, I had no more error, but emails did not appear at all, neither in the category nor in the error logs.

In `containers/mail-receiver.yml` we’ve got:

```plaintext
POSTCONF_relay_domains: forum.example.net, example.net

```

(Of course, `example.net` is not what’s actually in the configuration file. What’s in there is the hostname for the forum and the parent domain name, both of which are configured in the DNS)

I noticed that @mpalmer mentioned years ago that adding a second domain could be done but

So I expected the little `relay_domains` configuration to not be enough, but it seems to work, given that you `git pull` before rebuilding. There must be _some quirk_ in the way `mail-receiver` container is built that fails to update pups…
