Thanks for this hint! I'm not quite sure what would happen if the new
list were closed, would Sympa be smart enough to delete the manually
added aliases, or would also that removal need to be handled manually?

As I wrote on 2025-05-22 ("Subject: Correct way to rename list and
forward old address?") I had been unable to figure out the "proper"
way to do this – clearly this would be it.

What I ended up doing at that point was simply to add

old-listname:    address@concealed

in /etc/aliases which will produce bounces of the format

551 User has moved; please try address@concealed
