lewismc opened a new issue #10:
URL: https://github.com/apache/incubator-ponymail-foal/issues/10
When one executes the set up i.e. `python3 tools/setup.py` and selects the
default value [*] for the following prompt
```
Which domains would you accept mail to from web-replies? [*]: *
```
The resulting `server/ponymail.yaml` includes the following `ui` code block
```
ui:
...
sender_domains: *
```
This cases a fatal `yaml.scanner.ScannerError`
```
% python3 server/main.py
