So I have to create the list with the original name plus a unique trailing and after create mail alias and let postfix rewrite the destination from the alias to the real name before passing the mail to mailman, correct?
You don't want Postfix to rewrite the name. That's more complicated than you need and not what you want anyway because it would expose the 'true' name in the To: header of outgoing posts.
What you do is the following:
For listx in domain example.com, you create the list as listx_example.com or however you want to append domain to name to make it unique. You also add listx@example.com to acceptable_aliases for the listx_example.com list.
For postfix, considering only the list posting address (the others are similar) In the normal case for the listx@example.com list you would have a virtual_alias_maps entry like
listx@example.com listx
and an alias_maps entry like
listx: "|/path/to/wrapper post listx"
Instead of these, you would have a virtual_alias_maps entry like
listx@example.com listx_example.com
and an alias_maps entry like
listx_example.com: "|/path/to/wrapper post listx_example.com"
