Ah, I didn’t recognize you mean this.

Since the mail goes through the mailing list software, the sender must not be the original sender any more – ntg.nl is not allowed to send emails for a different domain. Many securely configured mail servers reject “faked” sender addresses, as they should. Look up DANE etc.

That's all well and good but it obscures the sender in your mail client. If you look at the screen shot you can see that the older emails all display the sender's name in the list. Under the new system (just the topmost entry, shown selected) every email comes from "ntg-context@ntg.nl" which is completely useless when you want to visually scan down the list for a particular person.
