I never had any nametrans for the local part, so no reverse nametrans.
But you are right with that it's now necessary.

And it does, although i used the reverse function from my example above. 

def localtransfolder_KVA(foldername):
    if(foldername == "KVA"):
        retval = "INBOX"
    else:
        retval = re.sub("KVA\.", "", foldername)
    retval = re.sub("\.", ".", retval)
    return retval

So i guess that 6.5.3.1 is more accurate and correct then 6.5.2.1 was, although
6.5.2.1 already had the reverse nametrans feature.
