This discard is saying that there was no syntactically valid email
address found in any of the places it looks. These are defined by the
mailman setting `sender_headers`, the default for which is `from from_
reply-to sender` which means
- the From: header
- the unix from or envelope sender
- the Reply-To: header
- the Sender: header
Have you set
```
[mailman]
sender_headers: ...
```
in mailman.cfg?, and if so, to what?
