You're right. I didn't look closely enough this morning. Mental Note:
Do not answer e-mails before first coffee. I am sorry.

you probably typed exim4 -d -bt cheako@filbert.is-a-geek.org

That looks like a DNS issue. For a host with only an A record, it should say:
|DNS lookup of brokenmx-a.zugschlus.de (MX) gave NO_DATA
|returning DNS_NODATA
|DNS lookup of brokenmx-a.zugschlus.de (AAAA) gave NO_DATA
|returning DNS_NODATA
|DNS lookup of brokenmx-a.zugschlus.de (A) succeeded
|fully qualified name = brokenmx-a.zugschlus.de

Please give the output of
dig filbert.is-a-geek.org any

In the mean time, maybe

filbert.is-a-geek.org: 10.0.0.20

in /etc/exim4/hubbed_hosts can help. This will take the routing
decision from DNS to the local file.

You may be right. The DNS is an issue here.
