This is not possible to do reliably in email due to the control of the relevant information by email authors.
Just wondering... I can see that the above would be true in the case of lists that allow anybody to post. But is it true even in the case of lists that can only be posted to by subscribers?
(Well, I guess that Subscriber A could spoof their message as being from Subscriber B. But barring pathological cases like that,
Or subscriber B could lend their phone to subscriber A to write a quick reply.
presumably Mailman can match the sender's email address against the subscriber list and find the value of the corresponding name field.)
If somebody writes the code and installs it, yes. Most of the code is already there, somewhere, it's just that it's only used for messages from Mailman to the subscriber. This requires not just coding skills, but also access (usually root) on the server.
