question about org-link gnus message and gnus registry

[physiculus <physiculus@gmail.com>]

hello,
i'm just struggeling about the consistency of an org-link to a gnus message
after moving this message into another folder on same server or a
different one.

scenario:
i create a org link with org and insert the link into an org file.
works.

now i move the message inside gnus to another folder.

open the link inside the org file is not valid anymore.

i thought, that the registry is responsible for saving the position of
any message. therefore it saves the message-id and use this to locate
the message.

and i thought, that org-link "knows" this message-id, though the link to
the message is valid without the position of the folder or better the
position of the message inside the folder.
like a database index.
but now i'm quite sure, that my thoughts were completely wrong??
or is it possible to locate a message through org-link?

any ideas?

Regards
