With a little help from Bron I came to the following solution...

2.5 does not have xlist- and the only way to "migrate" it is to set it as
annotation to every mailbox.

It is possible to set it by connecting to the backend/server as admin user
authorized as the individual user and push eg.
. SETANNOTATION INBOX.Trash "/specialuse" ("value.priv" "\Trash")
commands. Maybe I get this to work over my 2.4 frontends as well.

On 2.5 the new SETMETADATA is available as well...
. SETMETADATA INBOX.Sent ("/private/specialuse" "Sent")
